SI unit of permeability is

A

`(Am)/T`

B

`(Tm)/A`

C

`T/(Am)`

D

`A/(Tm)`

Text Solution

Verified by Experts

The correct Answer is:
B
`dB=mu_(0)/(4pi)*(Idlsintheta)/r^(2)`
`thereforemu_(0)=(4pidBr^(2))/(Idlsintheta)`
Since, `4piandsintheta` are unitless,
`therefore` Unit of `mu_(0)=(Tm^(2))/(Am)=(Tm)/A`
