Front

Circuit

Back

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

Front

Repulsion

Back

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

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

Speaker

Back

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

Front

Quantify

Back

To measure or express something as a number, such as determining the strength of a magnetic field or the amount of electric current in a circuit.

Front

Magnetic Field

Back

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

Front

Electric Current

Back

The flow of electric charge, typically measured in amperes (A), which moves through a circuit.

Front

Voltage

Back

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

Front

Resistance

Back

The opposition to the flow of electric current, measured in ohms (Ω).

Front

Conductor

Back

A material that allows electric current to flow easily, such as copper or aluminum.
