AQA GCSE Physics: Magnetism and Electromagnetism

These flashcards cover key vocabulary terms and definitions related to magnetism and electromagnetism in AQA GCSE Physics.

Permanent Magnets

Magnets that are always magnetic and always have poles.

Induced Magnets

Materials that become magnetic when in the presence of a magnetic field, but do not have fixed poles.

Magnetic Field

An invisible force field around a magnet, illustrated by field lines pointing from the north to the south pole.

Right Hand Grip Rule

A rule used to determine the direction of a magnetic field around a current-carrying wire.

Solenoid

A coil of wire that produces a magnetic field when an electric current passes through it.

Motor Effect

The interaction of two magnetic fields that results in a force on the wire carrying current.

Fleming’s Left Hand Rule

A rule to determine the direction of force on a current-carrying conductor in a magnetic field.

Electromagnetic Induction

The process of generating a potential difference across a conductor when it is moved through a magnetic field.

Dynamo

A device that converts mechanical energy into direct current (DC) electricity.

Transformer

A device that changes the voltage of alternating current (AC) by using coils of wire.
