Question

Dimensional formula for intensity of magnetising field and magnetic susceptibility are.
  1. [M0A2L1T2]  [M0ALT1]
  2. [M0AL1T0]  [M0A0L0T0]
  3. [MLT2]  [ML2T2]
  4. [M0A1L1T2]  [M0A0L0T0]


Solution

The correct option is B [M0AL1T0]  [M0A0L0T0]
H=Bμ0=ni
(for solenoid having vacuum in core)
=A/meter=[M0A1L1T0]
X=IH=A/mA/m=[M0L0A0T0]
[M0AL1]T0]  [M0A0L0T0]
