Magnetisation and Magnetic Poles

After the magnetic materials are transformed into the required shapes, sizes and designs, the formed pieces have to be magnetised before they can be put to use.

The magnetisation is done by electric current; and for this purpose, electromagnetising machines are used these days, as they are convenient and powerful. By this magnetisation process, the formed pieces develop North polarity on one end or side and South polarity on the other end or side, in a very short time, namely, seconds. Magnetisation does not take long time if one has a “charger” or “magnetiser”, and knows how to operate it.
