Magnetism and EM Waves - Vocabulary Flashcard

Front

Radiant Energy

Back

This is an energy that is most closely tied to the frequency of electromagnetic waves or the momentum of a photon.

Front

Magnetic Domain

Back

These are the atoms with partial magnetism that are all arranged along the same direction in a permanent magnet.

Front

Magnetic Pole

Back

These are the areas of a permanent magnet where the magnetic field is the strongest, usually one at each end of the magnet.

Front

Electromagnet

Back

This is when the magnetic domains within a piece of metal (like a nail) are oriented by an electrical current, making a very strong temporary magnet.

Front

Photon

Back

This is the 'particle' component of an electromagnetic wave, as electromagnetic waves travel as both a particle and a wave.

Front

Electromagnetic Waves

Back

These are waves of energy that travel through space and are composed of oscillating electric and magnetic fields.

Front

Magnetic Field

Back

This is the region around a magnet where magnetic forces can be detected, represented by field lines.

Front

Permanent Magnet

Back

This is a material that maintains a persistent magnetic field without the need for an external power source.

Front

Electric Generator

Back

This is a device that converts mechanical energy into electrical energy using electromagnetic induction.

Front

Electric Motor

Back

This is a device that converts electrical energy into mechanical energy using magnetic fields.
