Question

State Ways of magnetising an iron bar?

Answer 1

Lay the bars in a circuit.Place the four pieces of iron or steel on a flat surface. Arrange them in a circuit pattern. Place one bar horizontally. At each end of the horizontal bar, place a vertical bar. At the lower ends of the vertical bar, close the circuit with another horizontal bar. The bars should form a square. Place a piece of soft iron at the right side of the circuitMove the horseshoe magnet over the barsHold a horseshoe magnet over the circuit. The ends of the magnet should correspond to the two horizontal bars. Touch the magnet ends to the two bars at the left sides. Move the magnet to the right. At the end, slide the magnet off the bars onto the soft iron. You may substitute the horseshoe magnet with two bar magnets.Repeat the processRepeat this process several times, always moving the magnet in the same direction. Do not move the magnet backward and forward.

Answer 2

hold a bar magnet vertically at one end of iron bar. rub the magnet along the length of iron bar, till you reach its other end and bring it back. repeat this process for at least 40-50 times till the iron bar get magnetise
