Magnetism and Energy Concepts

Front

Magnetic field

Back

The area around a magnet in which there is magnetic force.

Front

Poles

Back

The ends of a magnet, where the magnetic force is strongest; typically labeled North (N) and South (S).

Front

Attraction

Back

The force that draws magnets with opposite poles together.

Front

Repulsion

Back

The force that pushes magnets with the same poles apart.

Front

Kinetic Energy

Back

Energy of motion.

Front

Potential Energy

Back

Stored energy due to an object's position or state.

Front

Electromagnet

Back

A magnet created by an electric current flowing through a coil.

Front

Permanent Magnet

Back

A material that retains its magnetism even after the magnetizing force is removed.

Front

Polarity

Back

The direction of a magnetic field, typically from North to South.
