Electric and Magnetic Fields

Front

What creates electric fields?

Back

Electric fields are usually created when electrons are transferred between objects.

Front

What happens to the force on a paper clip when the distance from a magnet decreases?

Back

The force on the paper clip increases.

Front

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by using more coils.

Front

What type of charge is attracted to a positively charged object?

Back

Only negative charges are attracted to a positively charged object.

Front

What do fields allow objects to exert on each other?

Back

Fields allow objects to exert forces on each other without touching.

Front

What is an electric field?

Back

An electric field is a region around a charged object where other charged objects experience a force.

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be observed.

Front

What is the relationship between electric current and magnetic fields?

Back

Electric current flowing through a wire creates a magnetic field around the wire.

Front

What happens to the strength of a magnetic field as you move away from the magnet?

Back

The strength of the magnetic field decreases as you move away from the magnet.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
