2 A physics teacher suspends two pointers in a magnetic field. One pointer is made of brass and the other is a magnet. She holds the pointers in the initial positions shown in the two upper circles of Fig. 7.1. She then releases the pointers. brass pointer draw final position of brass pointer in this circle N pole of magnet arrows show direction of strong magnetic field draw final position of magnet in this circle Fig. 7.1 S pole of magnet (a) In the lower circles of Fig. 7.1, draw the settled final positions of the two pointers. (b) (i) Explain the final position of the brass pointer. (ii) Explain the final position of the magnet. [2] [2]
