Question

Which one of the following statements is true? (Only one is true and explain each one)

a) Usually, mechanically hard materials are magnetically soft.

b) Magnetic permittivity and magnetic susceptibility are materials properties that are commonly used to characterize the response of materiasl to applied magnetic fields.

c) When a ferromagnetic material is exposed to an applied magnetic field, domains in the net magnetic momentum is better aligned relative to the field will grow at the expense of domains in which the net magnetic momentum is poorly aligned relative to the field.

d) So-called high-temperature superconductors (those that display superconducting properties at temperature above -196C) are not made from ceramics.

e) Chromium is both paramagnetic and antiferromagnetic

Explanation / Answer

Ans: b) Magnetic permittivity and magnetic susceptibility are materials properties that are commonly used to characterize the response of materiasl to applied magnetic fields
