A solenoid has a core of a substance with relative permeability 600. What is the magnetic permeability of the given substance?

A

`20pixx10^(-5)NA^(-2)`

B

`21pixx10^(-5)NA^(-2)`

C

`22pixx10^(-5)NA^(-2)`

D

`24pixx10^(-5)NA^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
D
As, `mu=mu_(r)mu_(0)`
`"Here", mu_(r)=600 and mu_(0)=4pi xx10^(-7)NA^(-2)`
`therefore "Magnetic permeability"`
`mu=600xx4pixx10^(-7)=24pixx10^(-5)NA^(-2)`
