Question 50: 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
$$-$$5
