Question

Quizplus · Accepted Answer

Retentivity is the ability of a material to retain its magnetization even after the external magnetic field is removed.

Answer: A
 Magnetic flux is the amount of magnetic field passing through a given area.

Answer: E
 Permeability is the measure of a material's ability to conduct magnetic flux, or to permit the movement of magnetic lines of force.

Answer: H
 Ferromagnetic materials like iron, cobalt and nickel, exhibit strong magnetic properties which can be easily magnetized or demagnetized.

Answer: G
 Paramagnetic materials like aluminum, platinum and manganese, display weak magnetic properties and are only slightly attracted to magnetic fields.

Answer: C
 Tesla is the unit used to measure the strength of a magnetic field.

Answer: D
 Electromagnets are made by wrapping a wire around a magnetic core, and are used to generate a strong magnetic field when an electric current is applied.

Answer: B
 Spin magnetic moment is the intrinsic magnetic moment of an elementary particle, such as an electron, which arises from its spin.
