K.C.S.E Physics Q & A - MODEL 2000PP1QN12

​ Fig. 7 shows how magnets are stored in pairs with keepers at the ends

​Explain how this method of storing helps in retaining magnetism longer.

ANSWER

• The keepers become magnetized thus neutralizing the pole, this reduces repulsion at the poles, thus helping in retention of magnetism
