उत्तर
We’ll take a bar magnet and point the north pole towards the car, then the south pole is at the front of the car if the automobile is attracted to it. If it is rejected, it indicates that the North Pole is in front of the vehicle. The magnet’s attraction and repulsion cause this phenomenon. Poles that are similar repel each other, whereas poles that opposite attracts each other.
