B^(2)/(mu(0)), where B is magnetic induc...

`B^(2)/(mu_(0)),` where `B` is magnetic induction and `mu_(0)` is permeability of free space, has the same dimensions as :

A

energy

B

energy density

C

magnetic intensity

D

none of these.

Text Solution

Verified by Experts

The correct Answer is:
B
Here `B=MT^(-2)A^(-1)` and `mu_(0)=MLT^(-2)A^(-2)`
Now `(B^(2))/(mu_(0))=(M^(2)T^(-4)A^(-2))/(MLT^(-2)A^(-2))`
`=[ML^(-1)T^(-2)]`
=energy density.
Hence correct choice is `(b)`.
