Fundamentals of Magnetism

Vocabulary flashcards covering the fundamentals of magnetism, material classifications, and physical properties as defined in aviation and general science.

Magnetism

The force exerted by magnets when they attract or repel each other, caused by the motion of electric charges.

ACS code $AM.I.A.K2$

The code associated with Subject A - Fundamentals of Magnetism in General Section $1$.

Magnetism (Aviation Definition)

The property of an object to attract certain metallic substances.

Ferrous materials

Materials composed of iron or iron alloys, such as soft iron, steel, and alnico.

Magnetic materials (Nonferrous)

At least $3$ substances—nickel, cobalt, and gadolinium—that are magnetic to a limited degree.

Nonmagnetic

Substances that are not attracted to magnets, such as copper and gold.

Diamagnetic

Non-magnetic substances that are repelled by both poles of a magnet.

Attraction and Repulsion

The principle where opposite poles (North and South) attract each other, while like poles (North-North or South-South) repel.

Atoms

Tiny units making up every substance, containing electrons which are particles that carry electric charges.

Magnetic Fields

Invisible areas created around magnets that exert force on magnetic materials.

Ferromagnetism

The characteristic magnetic properties stemming from metals like iron, cobalt, and nickel.

Unpaired electrons

Atomic particles in magnetic materials that can be aligned to create a magnetic field.
