Question 49: Magnetism and Matter

Question

The space inside a straight current carrying solenoid is filled with a magnetic material having magnetic susceptibility equal to 1.2 $	imes$ 10
$-$5
. What is fractional increase in the magnetic field inside solenoid with respect to air as medium inside the solenoid?

Accepted Answer

$\overrightarrow {B'}  = {\mu _0}(1 + X)ni$ (in the material)
$\overrightarrow {B'}  = {\mu _0}ni$ (without material)
So fractional increase is
${{B' - B} \over B} = X = 1.2 	imes {10^{ - 5}}$

Answer

1.2 $	imes$ 10
