High School Science Project Creating a Magnet With Electricity [sciencetechnology-center.blogspot.com]

Make a science project using electricity to make a magnet

This is great for demonstration at the science fair and is good for high school age students.

Go to your local hardware store and get the following items:

A nail (you will need a long nail that is at least 3 inches long.) D Batteries - you will need 2 of these Thin wire A wire cutter Masking tape Electric tape Paper clips A "knife" switch - you can buy one of these at Radio Shack or have it ordered out of the catalog. I believe it costs about $ 3.00.

Here are the instructions to make the magnet:

Taking your thin wire leave about 6 inches of wire hanging and then start wrapping the wire tightly around the long nail. You will want to wrap it around 60 times. When you are done let another 6 inches extra wire hang from that end of the nail and cut. Set your two batteries next to each other and the knife switch next to them. Take the nail with wire wrapped around and face it so that the head of the nail is on your left and the point is on the right. Take the excess wire hanging from the point of the nail and bring to the bottom of one of the batteries. This is the negative side and using the masking tape tape it to the bottom. Make sure the wire it touching the battery. Now take the excess wire that is hanging from the nail head and attach it to a terminal on the knife switch. Now cut two extra pieces of wire about 8 inches each. The first one tape onto the top or positive end of the battery which you attached the wire from the nail and bring the other end of the wire and attached with tape to the bottom or negative end of the 2nd battery. With the second piece of wire tape an end to the top or positive end of the second battery and attached the other end to the other terminals on the knife switch. Now if you push the top of the knife switch to close it you will have closed the circuit and now create electricity running through the wires and all around the nail. Do not hold the nail as it has electricity running through it. Let it lay down on the table.

Using your paperclips bring them close to the nail and see if they are magnetized. To understand this you need to know that when current from electricity goes through the wire wrapped around the nail it makes the magnetic field. The field is extending in circles which keep expanding outward. When you twist the wire into a coil it is called a solenoid. Because the wire is coiled the magnetic field twists which causes the magnetic energy to stay inside the area of the coiled wire. This is a very strong magnet which is termed an electromagnet.

When this electromagnet is created it causes all the fields to go one way which are consistent with a magnet and creates a north and south pole. This makes it strong enough to pick up things like a small paper clip.

Let's see how strong your magnet is. See how many paper clips you can pick up. What if you make the magnet with only one battery. How weak is that battery compared to one with two batteries?

This science p roject is great for the demonstration at the science fair.

Question by : How do creationists decide when to reject science? I have a microbiology professor (who shall remain unnamed) who rejects biological evolution and the scientifically determined age of the earth in favor of the bible. When it comes to the treatment of leprosy, however, he seems to favor science over the biblical two-doves-and-a-lamb prescription. This leads me to ask the question, how do creationists and so-called biblical literalists decide when they will eschew science in favor of their holy book, and when they will toss out holy book passages in favor of science? Best answer for How do creationists decide when to reject science?:

Answer by Transposed
"How do creationists decide when to reject science?" Simple, when it suits them. "I have a microbiology professor ... who rejects biological evolution..." Do yourself a favor and find a teacher that acknowledges factually observed phenomenon.

Answer by CK
When it is convenient and/or beneficial for them to do so.

Answer by Peloristic Atheist (A)
Whenever it's convenient for them.

Answer by Iason Ouabache
If science disagrees with an ultra-literal interpretation of the Bible then it isn't "True Science".

Answer by Ribbi
You'll find that they are quite inconsistent.

Answer by Congolia Breckenridge
Who says anyone has to conclusively reject either? Science and faith are both disciplines that leave a lot to be desired. IOW, science must always leave open the possibility that future data will change the science, faith must leave open the possibility that future revelation will change the religious interpretation.

Answer by MPH
I will never toss out the bible for any reason. Even atheists don't accept all science. It isn't perfect.

Answer by Arch
They don't reject science at all. It isn't really SCIENCE until it is PROVEN!!! Evolution is not PROVEN, no matter how many times Richard Dawkins claims that it is. As far as a scientifically determined age to the earth, there are several mathematical flaws with radiometric dating. I reject it on mathematical (one of my areas of expertise) grounds alone.

Answer by Hannah Brooks
Okay, I will give you a creationists TRUE opinion. You want to hear from one and get their point of view on this subject, not just hear from a bunch of atheists that will call me stupid and ignorant, when I am not. I know the theories on evolution. Yes, evolution is a theory. I do not 'reject' science, because I know the facts behind a lot of science. I will believe in my God over what a scientist says when I feel that it does make sense to me. For example, if we evolved from monkeys, why are there stil monkeys on earth? But. I believe in stuff like how a virus works, or how plants turn CO2 into 0xygen. It just depends on the person, really. I listen to my heart on what I think is true and false.

Answer by Joseph the Gray
I am a christian, you are not. I will speak for me, you speak for who cares. Christians are not opposed to science. Some who claim they represent science oppose God however. We laugh at their ignorance. Our God is science. Who else would know how to take nothing and make everything? Only the Master Scientists that's who. Man's wisdom is foolishness to God. True science has always been on our side.

Answer by jeshurun
When do I? When the spiritual direction of science conflicts with the spiritual direction from the Bible. The Bible is: Historically accurate, scientifically correct, and contains 100% reliable prophecies. The world of Science will never achieve the same.

Answer by Te Rex
. I have yet to meet any Christian who rejects science - As a result of medical science I am still alive, you see, I am a 15 year Cancer survivor, and a couple of years ago I had heart surgery, and should be dead - - - I am a 75 y o Christian, B.A. & Y.E.C. . . When science disagrees with God's Word, the Holy Bible, it is the science that is wrong. e.g. according to the calculation of the facts given in the Bible this earth is about 6,000 years old, not many billions as some of God's unbelievers seem to think. .
