Electromagnets

A continuous flow of electric charges from one region to another

A type of magnetic field

A form of light energy

A chemical reaction

To measure electric charge

To measure voltage

To measure resistance

To generate electricity

Electromagnetism is the interaction between electricity and magnetism.

Changing the shape of a wire changes the shape of the magnetic field.

A straight wire generates a stronger magnetic field than a looped wire.

Changes in the magnetic field can affect electric charges.

To create an electric current that generates a magnetic field

To provide light for the experiment

To measure the resistance of the wire

To cool down the coil

The electromagnet becomes stronger

The electromagnet becomes weaker

The electromagnet stops working

The electromagnet reverses polarity

Moving the magnet more quickly near the wire

Using a stronger magnet

Increasing the number of loops in the wire

Keeping the magnet stationary

By creating a magnetic field when current flows through a coil

By heating up the metal objects

By producing light energy

By chemically reacting with the metal
