I am in class 6 and have been given a holiday homework to make a toy which uses a magnet. please help!?

Answer 1

To do this, you will need three things: a small, plastic toy car or truck and two magnets. You can buy two "domino" ceramic magnets for about $1.50 at the hardware store – they come in packs of two, and are about the size of dominoes. Attach one magnet inside the vehicle so that its poles face forward and backward. Now, by moving the other magnet so that its pole either matches or is opposite, you can make the vehicle move forward or backward.

By the way, an interesting fact about magnets is this: if you were to break one of the ceramic magnets above into two pieces – each piece would be just as strong as the other, and just as strong as the original magnet, but the instant you break it, the poles reverse.
