(a) You are provided with a 15 cm long steel strip.
By using a permanent bar magnet explain how
you will magnetise the steel strip.
​

Answer 1

Answer:

Hold the steel object in one hand. Stick the magnet anywhere on the steel about halfway along its length, then drag it to one tip. Repeat several times, stroking only in one direction, and only along half of the steel. The more you do this, the more magnetized the steel will become.
