Relative permitivity and permeability of a material `epsilon_(r) and mu_(r)`, respectively . Which of the following values of these quantities are allowed for a diamagnetic material?
A
`epsilon_(r ) = 0.5, mu_(r ) = 1.5`
B
`epsilon_(r ) = 1.5, mu_(r ) = 0.5`
C
`epsilon_(r ) = 0.5, mu_(r ) = 0.5`
D
`epsilon_(r ) = 1.5, mu_(r ) = 1.5`
Text Solution
Verified by Experts
The correct Answer is:
B
For a diamagnetic material , the value of `mu_( r )` is less than one. For any material , the value of `epsilon_(r)` is always greater than `1`.
