Magnetic Properties

What is the phenomenon where materials attract or repulse with either materials

• Parallelism
• Attraction
• Magnetism
• Repulsion

Magnetic forces are generated by moving electrically charged particles

• True
• False

Which the following arises from the intrinsic spin of electrons

• Orbital Magnetic Moment
• Internal Spin Motion
• Electron Rotation Moment
• Spin Magnetic Moment

Certain metallic materials possess a permanent magnetic movement in the absence of an external field and manifest very large and permanent magnetization.

• Ferromagnetism
• Ferrimagnetism
• Diamagnetism
• Paramagnetism

In ferrimagnetism, magnetic movements have opposing moments however, ______?

• antiparallel moments cancel each other out
• antiparallel moments do not cancel each other out
• parallel moments do not cancel each other out
• parallel moments cancel each other out

An example of antiferromagnetism is

• Ferrous Sulfate
• Manganese Oxide
• Sodium Chloride

In ________ substances, the electron orbits produce small magnetic fields that oppose the external magnetic field

• Diamagnetic
• Paramagnetic
• Ferrimagnetic
• Ferromagnetic

This origin of magnetic moments results from the orbital motion of electrons around a nucleus.
