Electromagnetic Forces 1

Front

What is a generator?

Back

A device that converts mechanical energy into electrical energy, often using a magnet moving through a coil of wire.

Front

What happens when you walk across a carpet in socks?

Back

You pick up charges due to friction, which can later transfer to another object.

Front

What is created when a magnet moves through a coil of wire?

Back

An electric current.

Front

What is an electric motor?

Back

A device that converts electrical energy into mechanical energy.

Front

What is an insulator?

Back

A material in which electrons are not able to move easily, preventing the flow of electricity.

Front

What is electromagnetic induction?

Back

The process of generating an electric current by changing the magnetic field around a conductor.

Front

What is a solenoid?

Back

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

Front

What is a conductor?

Back

A material that allows electrons to move easily, facilitating the flow of electricity.

Front

What is a ferromagnet?

Back

A material that can be magnetized and retains its magnetic properties.

Front

What is resistance in an electrical context?

Back

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