8.3 Induced Magnetism
Magnetic material such as iron or steel can be made into a magnet. This is known as magnetization. In other words, we can say that magnetism has been induced in it.
If a piece of iron is placed near a strong magnet, the S-pole of the true magnet induces an N-pole in the near end of the piece of iron, while the far end of the iron piece becomes an S-pole.
It should be noted that the induced magnetism vanishes as the true magnet is removed.
