SSC JE Electrical Engineering 24 Jan 2018 Evening Paper

A diamagnetic material has a constant Relative permeability slightly less than 1.
Diamagnetic materials are Repelled by a magnetic field.
${\mathit{\mu }}_{\mathit{r}}={\mathit{x}}_{\mathit{e}}-1$
${\mathit{x}}_{\mathit{e}}$ = magnetic Susceptibility

Magnetic susceptibility is less than 1.
