Magnetic Force
The location of the strongest parts of a magnetic field.
What are the magnetic poles?
The invisible region around any charged object where an electric force is applied.
What is an electric field?
The movement of electric charges through a closed circuit.
What is a current?
A temporary magnet made with a current carrying wire coil wrapped around a magnetic core.
What is an electromagnet?
One of the best materials for conducting electricity.
What is copper?
The region around a magnet where the magnetic forces act.
What is the magnetic field?
A material through which electrons (charges or current) can move easily.
What is a conductor?
When a circuit is complete and electric energy flows through the circuit.
What is a closed circuit?
The field that surrounds an electric current.
What is a magnetic field?

The needle of this wayfinding device acts as a magnet.
What is a compass?
An object with equal amounts of positive and negative charge.
What is electrically neutral?
The element needed in a circuit that powers the device.
What is an energy source?
By increasing the number of coils or increasing the current through the coiled wire.
What is how to increase the strength of an electromagnet?
What is conduction?
Increases the magnetic potential energy of the magnet.
What is decreasing distance between like or unlike poles?

What is an electrically charged object?
Stops the flow of electricity and includes materials such as plastic, rubber, ceramic, and glass.
What is an insulator?
Uses a direct current to transfer electric energy into mechanical energy.
What is an electric motor?
A device that uses a magnetic field to transfer mechanical energy to electric energy.
What is an electric generator?
The arrangement of the atomic structure of a material that can be organized in order to be magnetized.
What are/is the magnetic domain/s?
The larger the charges or the greater the distance between the two charges, the greater this will be.
What is electric potential energy?
The measurement of the electric potential energy in a circuit between two points.
What is voltage?
An electric current that changes direction in a regular pattern.
What is an alternating current?
Increasing the number of coils, using a stronger magnet, or increasing the speed of motion of the magnet.
What can increase the amount of current a generator produces?
