A) ferromagnetism
B) ferrimagnetism
C) diamagnetism
D) paramagnetism
Correct Answer: C
Solution :
Super conductor is a perfect diamagnetic because diamagnetic substances are always temperature independent. In super conductor abnormal relation in seen between resistance of temperature. Here R decreases with decrease in temperature-but at certain minimum temperature. R drops to zero on further decreases in temperature R is unchanged.
