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

Front

What is the primary function of a compass?

Back

To find north.

Front

What is the relationship between electric and magnetic fields?

Back

They are closely tied and affect one another.

Front

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

Back

It becomes stronger and more concentrated.

Front

How can the principles of electromagnetism be used to generate electricity?

Back

By moving a magnet through a coil of wire.

Front

What is the core of a solenoid?

Back

The object around which the wire is wrapped.

Front

Define electromagnetism.

Back

The interaction between electric currents and magnetic fields.

Front

What is a magnetic field?

Back

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

Front

What is the role of electric current in generating a magnetic field?

Back

Electric current creates a magnetic field around the wire.

Front

What is a solenoid?

Back

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

Front

Explain how a compass works.

Back

A compass has a magnetized needle that aligns itself with the Earth's magnetic field, pointing towards magnetic north.
