Therefore, if one edge of an iron bar is pushed away by a bar magnet's north pole then certainly it is a magnet.
Explanation:
- Repulsion is Magnetism's surest test. Since a magnet can attract both a magnet and another magnetic object, it can only repel a magnet and not another magnetic material.
- Therefore, if one edge of an iron bar is pushed away by a bar magnet's north pole then certainly it is a magnet.
- When the north pole attracts both edges of the bar this means it's just a magnetic object.
- And if it were a magnet then one of the edges of the iron bar would've been repelled by the magnet's north pole.
