Answer to Question #247097 in Physics for Reena Biswas

Question

The magnetization within a bar of some metal alloy is 1.2×106 A/m when the H field is 200 A/m.

The magnetic susceptibility χm of this alloy is,
a, 4000
b, 4560
c, 5400
d, 6000

Answer 1

Magnetic susceptibility of the alloy can be found as follows:

$$\chi_m=\dfrac{M}{H}=\dfrac{1.2\cdot10^6\ \dfrac{A}{m}}{200\ \dfrac{A}{m}}=6000.$$

Answer:

d. 6000
