Objective
You will be making an electromagnet using coils of wire. The aim of such science fair experiments is to test how strong electromagnets can be. You will also determine how the magnetic field strength is affected by the number of times the wire is wrapped around while making the magnet.
Introduction
A magnetic field is produced when a current flows through a wire. The same can be proved in science fair experiments by using a magnetic compass. Since a single wire has a comparatively weak magnetic field, the wire can be coiled to observe that the magnetic field strength increases with each added coil.
You will find out how the magnetic field strength varies when the coil turns are increased. You will also find out how the coil should be oriented (parallel or perpendicular) in order to be effective.
Material
A 6V battery, alligator clips, magnetic wire, masking tape, paper clips (one box) or 200 steel washers (1 cm diameter) and three core material pieces of equal length such as iron nails or iron bolts or pieces of iron pipe.
Preparation
Three different electromagnets are to be made using core material of equal lengths. Now wrap the magnetic wire neatly around each piece of core material, but let the number of turnings be different for each piece. For example, one piece will be wrapped with 100 turns, the second with 200 turns and the third with 500 turns. Keep the coiled wire in place at both ends by attaching tape and leave at least 5 to 6 cm of extra wire for being connected to the battery. Using your utility knife, carefully remove the insulation of the free ends of the magnetic wire and expose 1 cm of copper wire.
The free ends are to be connected to alligator clips which are always used in science fair experiments. The alligator clips are to be attached to the terminals of the battery. Use a shallow tray to hold the paper clips (washers).
Procedure
Begin with the core material with 100 turns of coil.
Connect the alligator clips to the battery and hold the coil of the electromagnet parallel to the tray, touching the paperclips (washers) with the coil to pick them up. Move the coil out of the container and disconnect the battery. Now count how many paperclips were attached to the coil and write down the number in a table. Repeat the same procedure 4 times more and calculate the average of all 5 readings and write it down in the table. Now keep the coil of the electromagnet perpendicular, touching the paperclips (washers) with the coil. Move the coil out of the container and disconnect the battery. Now count how many paperclips were attached to the coil and write down the number in the table. Repeat the same procedure 4 times more and calculate the average of the 5 readings and write it down in the table. Next, take the coil with 200 turns and repeat steps 1 and 2. Then proceed with the coil with 500 turns and repeat steps 1 and 2.Make sure you record your findings without fail. Your table will consist of a whole bunch of numbers. Graphs are very important during science fair experiments. So plot a graph showing the results for each orientation. The X-axis should reflect the number of coils and the Y-axis should reflect how many paperclips (washers) were attached to the electromagnet.
When you look at the graph you may be amazed that all your efforts have been displayed by curved lines, which speak better than numbers.

God is the greatest scientist. Without God there would be no science. The Bible is not a book about science, but when it refers to science it is always correct. The Bibleâs Harmony With Scientific Facts. The Bible, at Job 26:7, speaks of God as âhanging the earth upon nothing.â Science says that the earth remains in its orbit in space primarily because of the interaction of gravity and centrifugal force. These forces, of course, are invisible. Therefore the earth, like other heavenly bodies, is suspended in space as if hanging on nothing. Speaking from Jehovahâs viewpoint, the prophet Isaiah wrote under inspiration: âThere is One who is dwelling above the circle of the earth, the dwellers in which are as grasshoppers.â (Isa 40:22) The Bible says: âHe [God] has described a circle upon the face of the waters.â (Job 26:10) The waters are limited by his decree to their proper place. They do not come up and inundate the land; neither do they fly off into space. (Job 38:8-11) From the viewpoint of Jehovah, the earthâs face, or the surface of the waters, would, of course, have a circular form, just as the edge of the moon presents a circular appearance to us. Before land surfaces appeared, the surface of the entire globe was one circular (spherical) mass of surging waters.â"Ge 1:2. Bible writers often speak from the standpoint of the observer on the earth, or from his particular position geographically, as we often naturally do today. For example, the Bible mentions âthe sunrising.â (Nu 2:3; 34:15) Some have seized upon this as an opportunity to discredit the Bible as scientifically inaccurate, claiming that the Hebrews viewed earth as the center of things, with the sun revolving around it. But the Bible writers nowhere expressed such a belief. These same critics overlook the fact that they themselves use the identical expression and that it is in all of their almanacs. It is common to hear someone say, âit is sunrise,â or âthe sun has set,â or âthe sun traveled across the sky.â The Bible also speaks of âthe extremity of the earthâ (Ps 46:9), âthe ends of the earthâ (Ps 22:27), âthe four extremities of the earthâ (Isa 11:12), âthe four corners of the earth,â and âthe four winds of the earthâ (Re 7:1). These expression s cannot be taken to prove that the Hebrews understood the earth to be square. The number four is often used to denote that which is fully rounded out, as it were, just as we have four directions and sometimes employ the expressions âto the ends of the earth,â âto the four corners of the earth,â in the sense of embracing all the earth.â"Compare Eze 1:15-17; Lu 13:29.
Answer by planner
i am not exactly sure what you mean by the relations and negatives...but in genesis chapter one we see that God created light before he created the sun. science tells us that the sun is the source of our light, but genesis 1:3-4 says that light and darkness are seperate entities from the sun or lack of the sun and in verses 14-18 we see that God created the sun and the moon on the 4th day, which was the day after he created grass and trees, etc. it says that he created the sun and the moon and the stars to determinethe seasons and the sun was created to rule over the day and the moon and stars to rule over the night. so there are several things there which disagree with science which says that light comes from the sun and that the grass and trees and so forth could not exist without the sun. but they were created the day before the sun was created, according to God's word. there is also a verse in genesis 2:19 which says that God created the animals out of the same dust of the earth from which man was created. that is most likely why scientist are confused about shared dna. humans were created from the same dirt God used to create the animals so naturally would have shared dna. then there is this verse in 1 timothy 6:20-21 "o timothy, keep that which is committed to your trust, avoid profane and vain babblings and oppositions of science, falsely so called, which some profession have erred concerning the faith"

Air has Weight: Job 28:25 To make the weight for the winds; and he weigheth the waters by measure All things made of Subatomic Particles invisible to the Naked Eye: Hebrews 11:3 By faith we understand that the worlds were prepared by the word of God, so that what is seen was not made out of things which are visible. Ocean Currents: Isaiah 43:16 Thus saith the LORD, which maketh a way in the sea, and a path in the mighty waters; Mountain and Valleys exist on bottom of Ocean: Jonah 2:5-6 5 The waters compassed me about, [even] to the soul: the depth closed me round about, the weeds were wrapped about my head. 6 I went down to the bottoms of the mountains; the earth with her bars [was] about me for ever: yet hast thou brought up my life from corruption, O LORD my God. http://www.creationists.org/scientific-foreknowledge-in-the-bible.html Medicinal Foreknowledge in the Bible: http://www.oldpaths.com/Archive/Lockwood/Germaine/Charles/1930/Cosmos/ch10.html
Answer by Victor Johnson
the science of the non-believers is not problematic(-al), but the science within the faith is Genesis 3:1-7 "Now the serpent(ie and lo (the) satan emanated/came from the "darkness" and it) was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden? And the woman said unto the serpent, We may eat of the fruit of the trees of the garden: But of the fruit of the tree which is in the midst of(ie beyond) the garden(viz. the occult/esoteric/yogic/vedic knowledge(-s)/science(-s) and abilities/activities), God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. And the serpent said unto the woman, Ye shall not surely die: For God doth know that in the day ye eat thereof, then your eyes(ie your occult/yogic/transcendental mind/senses) shall be opened, and ye shall be as gods, knowing good and evil(ie having (a) mind(-s)/omniscience/omnipotence as God). And when the woman saw that the tree was good(ie ostensibly Good) for food, and that it was pleasa nt to the eyes(videlicet to the dark side of mind), and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat. And the eyes(ie and the occult/yogic/transcendental mind/senses) of them both were opened, and they knew that they were naked(ie and from that moment on, they started to perceive all creations of the true Holy God as/like sinful and the occult/spiritual/religious iniquity as/like sinless); and they sewed fig leaves(ie false-prophecies) together, and made themselves aprons(ie and made themselves (a) satanic/human faith/spirituality).", 1 Corinthians 8:1-8 "Now as touching things(ie the religious/spiritual things) offered unto(ie which are (a) service/ministry of/to) idols(ie occult/spiritual/religious iniquities), we know that(ie usually the human tendency therein is that maybe) we all have knowledge(ie spiritual knowledge(-s) and abilities). Knowledge puffeth up, but charity(ie Love/Good(-ness)) edifieth(ie humbles). And if any man think that he knoweth any thing, he knoweth nothing yet as he ought to know. But if any man love God(ie the true Lord God), the same is known of him. As concerning therefore the eating(ie the following/exercising/practicing) of those things(ie of those spiritual/religious things) that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one. For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,) But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him. Howbeit there is not in every man(ie so far there is not in every cleric/believer/worshiper) that knowledge(ie that conscience/understanding): for some(ie some of them hereby) with conscience of the idol unto this hour eat it(ie exercise/practice (the/a) faith) as a thing offered unto an idol; and their conscience being weak(ie becoming weak so) is defiled. But meat(ie the occultism/idolatry/knowledgeable faith) commendeth us not to God: for neither, if we eat(ie if we exercise/practice it), are we the better; neither, if we eat not(ie if we not exercise/practice it), are we the worse."
