Sketch the magnetic field around a strong permanent bar magnet and a weak permanent magnet, so that it is clear, which is which, without labels.

In figure 16.2, the two bar magnets are attracting each other.

Label their four poles and draw force arrows appropriately to show magnetic force on each magnet.

The figure shows a horse shoe shaped magnet attracting a steel rod. The attraction shows that magnetic poles are induced in the rod.

State and explain what type of pole (N or S) must be induced in end A of the rod?
