Front

Speaker

Back

A device that converts electrical signals into sound using a magnet and a coil of wire to create vibrations.

Front

Magnet

Back

An object that produces a magnetic field and can attract certain materials, like iron, nickel, or cobalt.

Front

Wire

Back

A thin, flexible strand of metal that conducts electricity, often covered in insulation to prevent electric shocks.

Front

Circuit

Back

A complete, closed path through which electric current can flow, often including components like wires, batteries, and switches.

Front

Attraction

Back

The force that pulls objects toward one another, often observed between opposite poles of magnets or between a magnet and magnetic material.

Front

Repulsion

Back

The force that pushes objects away from each other, often seen between like poles of magnets.

Front

Magnetic Field

Back

The invisible area around a magnet where magnetic forces can be detected and influence other materials.

Front

Electromagnet

Back

A type of magnet created when an electric current flows through a coil of wire wrapped around a core, usually made of iron.

Front

Current

Back

The flow of electric charge, typically measured in amperes (A).

Front

Voltage

Back

The difference in electric potential between two points, measured in volts (V).
