Unit 14: Electricity and Magnetism

Front

What are the domains of a piece of metal?

Back

Regions within the metal where the magnetic moments of atoms are aligned. In an unmagnetized piece of metal, these domains are all mixed up.

Front

How are the domains organized in an ordinary piece of metal?

Back

The domains are all mixed up.

Front

What is magnetism?

Back

An invisible force produced by certain metals that can attract or repel other magnetic materials.

Front

What particles of an atom are attracted to each other?

Back

Protons and Electrons.

Front

What is a conductor?

Back

A material that allows the flow of electric current. Example: Copper.

Front

What is an insulator?

Back

A material that does not allow the flow of electric current. Example: Glass.

Front

What is the difference between a conductor and an insulator?

Back

Conductors allow electric current to flow, while insulators do not.

Front

What is static electricity?

Back

A buildup of electric charge on the surface of objects.

Front

What is the principle of electromagnetism?

Back

The interaction between electric currents and magnetic fields.

Front

What is an electric circuit?

Back

A closed loop that allows electric current to flow.
