Electricity and Magnetism

Front

What is a magnetic field?

Back

An area of magnetism surrounding a magnet that applies a force (a push or pull) without actually touching an object.

Front

What is magnetism?

Back

The force of attraction or repulsion of magnetic materials.

Front

What safety procedure should be followed when using iron filings?

Back

Keep hands away from eyes when using iron filings.

Front

How does an electromagnet demonstrate the relationship between magnetism and electricity?

Back

The wire in the electric circuit is wrapped around an iron core producing a magnetic field.

Front

What should you do if you are in a hurry during a science lab?

Back

Follow all directions when completing a science lab investigation.

Front

What is an electromagnet?

Back

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

Front

What materials are typically used to create a magnet?

Back

Iron, nickel, and cobalt are common materials used to create magnets.

Front

What is the difference between a permanent magnet and a temporary magnet?

Back

A permanent magnet maintains its magnetism over time, while a temporary magnet only exhibits magnetic properties when in a magnetic field.

Front

What is the role of an electric current in magnetism?

Back

An electric current flowing through a wire creates a magnetic field around the wire.

Front

What is the unit of measurement for electric current?

Back

The unit of measurement for electric current is the Ampere (A).
