Curie temperature is the one above which A vibration magnetometer consists of two identical bar magnets placed one over the other such that they are perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field is

{2^{5/4}}

s. One of the magnets is removed and if the other magnet oscillates in the same field , then the time period in second is The relative permeability of a substance
