Question

The unit of magnetic induction is

A) NM-1
B) NM-2
C) NA-1m-1
D) NM
plz give crt option ​

Answer 1

Explanation:

Before starting it is better to say that magnetic induction and magnetic fields- both are same. Since it is a very common quantity, its usual unit is Tesla (si unit) or Gauss (cgs unit) or Wb/m^2. Whereas

1 Tesla= 10000 gauss

But you can also express its unit in a different way.

The relationship with Lorentz force (F) with magnetic field (B) is-

F = qvB (taking magnitudes only)

q is charge and v is velocity. The unit of F is Newton (N), v is m/sec, q is coulomb (c). So B is

B= N sec/(c m)
