Answer 2

A toy car has a magnet laid hidden inside its body along its length.

To determine the poles of that magnet inside the toy, without breaking or opening the toy,we can easily do a simple thing.

We need another magnet to rub on that toy's external surface.

During this rubbing our external magnet will be repelled at a certain point,at that point the similar pole of the internal magnet is situated.

And the point where the external magnet is attracted,there is the opposite pole of the internal magnet is situated.
