Making of toy: 3 MARKS
Property/properties of magnet: 1 MARK

We can build many kinds of toys using magnets. One of the easiest one is to build a magical car which apparently can run on its own in any direction. The only things we require are a toy car and a pair of strong magnets. One of the magnets needs to be fitted under the car, and the other needs to be in the hand. So by putting the car with a magnet attached on the top of the table and putting the hand with another magnet beneath the table, we can have a magical toy car. As we will move the hand with magnet, the toy car will move accordingly in the direction our hand move. We need to remember if things do not fall in place we need to flip the magnet in our hand.
Properties of magnets that are acting here are:
1) Unlike poles of magnet attract each other.
2) Magnets can work through barriers.
