Conductors, Insulators, and Magnetism

Front

What is static electricity?

Back

Static electricity is an imbalance of electric charges within or on the surface of a material. It can be created by friction, which causes electrons to be transferred from one object to another.

Front

Where is the force of attraction the strongest on a magnet?

Back

The force of attraction is strongest at the poles of a magnet.

Front

Is a metal fork a conductor or insulator?

Back

A metal fork is a conductor.

Front

What device uses magnetism to show direction?

Back

A compass is a device that uses magnetism to show direction.

Front

What happens to particles with opposite charges?

Back

Particles with opposite charges attract each other.

Front

What happens to particles with the same (or like) charges?

Back

Particles with the same (or like) charges repel each other.

Front

Define a conductor.

Back

A conductor is a material that allows the flow of electric current or heat. Examples include metals like copper and aluminum.

Front

Define an insulator.

Back

An insulator is a material that resists the flow of electric current or heat. Examples include rubber, glass, and plastic.

Front

What is magnetism?

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

Front

What is a magnetic field?

Back

A magnetic field is the region around a magnet where magnetic forces can be observed. It is represented by field lines that show the direction and strength of the magnetic force.
