Question

Name the physical quantities of electro magnetic induction

Answer 1

electromagnetic induction means magnetic flux per unit area. or we can say that magnetic induction is the density of magnetic flux.

magnetic induction depends upon the following physical quantities :-

1. magnetic flux

2. cross section area.

now, dimensionally, magnetic induction [B] = [MT-2A-1] hence, dimensionally magnetic induction depends upon physical quantities :-

1. Mass ( with exponent 1)

2. time ( with exponent -2)

3. current ( with exponent -1)
