Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

How are magnetic forces different from other forces?

My father was named James Page Jackson because he was born on the old Jackson plantation in Lancaster county, Virginia. He named one of his daughters Lancaster for a middle name in memory of his old home. Clarice Lancaster Jackson was her full name. A man named Galloway bought my father and brought him to Arkansas. Some called him by the name of Galloway, but my father always had all his children keep the name Jackson. There were fourteen of us, but only ten lived to grow up. He belonged to Mr. Galloway at the time of my birth, but even at that, I did not take the name Galloway as it would seem like I should. My father was a good carpenter; he was a fine cook, too; learned that back in Virginia. I'll tell you something interesting. The first cook stove ever brought to this town was one my father had his master to bring. He was cook at the Anthony House. You know about that, don't you? It was the first real fine hotel in Little Rock. When father went there to be head cook, all they had to cook on was big fireplaces and the big old Dutch ovens. Father just kept on telling about the stoves they had in Virginia, and at last they sent and got him one; it had to come by boat and took a long time. My father was proud that he was the one who set the first table ever spread in the Anthony House.

What was the name of the first fine hotel in Little Rock?

Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.
When static electricity is not balanced, what happens to the charges?
