What materials are needed to build an electromagnet?

Back

To build an electromagnet, you need copper wire, a source of electric current, and a steel screw.

What do the blue lines represent when running a current through a wire?

Back

The blue lines represent a magnetic field that is created when current flows through the wire.

In what direction do magnetic field lines point?

Back

Magnetic field lines point from the north pole to the south pole of a magnet.

Front

What is the relationship between electricity and magnetism?

Back

Electricity can create a magnetic field, and a changing magnetic field can induce an electric current.

How can the strength of an electromagnet be increased?

Back

The strength of an electromagnet can be increased by increasing the current, adding more coils of wire, or using a stronger core material.

Front

What is the right-hand rule in electromagnetism?

Back

The right-hand rule is a mnemonic for understanding the direction of the magnetic field around a current-carrying wire: if you point your thumb in the direction of the current, your fingers curl in the direction of the magnetic field.

What is the significance of magnetic field lines?

Back

Magnetic field lines visually represent the strength and direction of a magnetic field; closer lines indicate a stronger field.
