According to Curie's law, the magnetic susceptibility of a substance at an absolute temperature T is proportional to

  1. 1/T
  2. T
  3. 1/T2
  4. T2

Answer

(1) 1/T

Solution

As per NCERT, Curie's law for a paramagnetic material: = C 0T, C being the Curie constant.

∴ 1T

A bar magnet is oscillating in the Earth's magnetic field with a period T. What happens to its period and motion if its mass is quadrupled?

  1. motion remains simple harmonic with time period = T2
  2. motion remains S.H.M. with time period = 2T
  3. motion remains S.H.M. with time period = 4T
  4. motion remains S.H.M. and period remains nearly constant

Two bar magnets having same geometry with magnetic moments M and 2M, are firstly placed in such a way that their similar poles are same side then its time period of oscillation is T1. Now the polarity of one of the magnets is reversed then time period of oscillation is T2, then

  1. T1 < T2
  2. T1 = T2
  3. T1 > T2
  4. T2 =
