Expert Answer

The figure shows the iron needles attached to the poles of a horse shoe magnet. The lower ends of the needles are attracted towards each other (or touch each other), since they have opposite polarities. The upper ends touching the poles of the magnet, have polarities opposite to that of the magnet. This phenomenon is called the magnetic induction.
