PS Unit 7 L4.2 - Analyzing Current and Magnetic Field

Front

What happens to the magnetic field when a wire is bent into a loop?

Back

It becomes stronger and more concentrated.

Front

What happens to the magnetic field if the electric current in a wire stops?

Back

The magnetic field would disappear.

Front

Why do solenoids produce stronger magnetic fields in a smaller space?

Back

Because the magnetic fields of different parts overlap and combine.

Front

What is the term used to describe the interaction between electricity and magnetism?

Back

Electromagnetism.

Front

How does changing the shape of a wire affect its magnetic field?

Back

It changes the shape of the field.

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be felt.

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.

Front

What is the right-hand rule in electromagnetism?

Back

A method to determine the direction of the magnetic field around a current-carrying wire.

Front

What is a solenoid?

Back

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

Front

How does increasing the current in a wire affect its magnetic field?

Back

It makes the magnetic field stronger.
