Aluminum has a magnetic susceptibility χ = 1.7 × 10-5 at t = 300 k. what will be the magnetization of a small sample of aluminum placed in a 1.5 t magnetic field at t = 150 k?

The magnetization of a small sample of aluminum is 40.6 A/m

Explanation:

Given that,

Magnetic susceptibility at 300 K

Magnetic field = 1.5 T

We need to calculate the magnetic susceptibility at 150 K

Put the value into the formula

We need to calculate the magnetization

Using formula of magnetization

Where, H = magnetic intensity

Formula of magnetic intensity

Where, B = magnetic field

Put the value of H into the formula of magnetization

Hence, The magnetization of a small sample of aluminum is 40.6 A/m

think its the third option
