Conductors, Insulators, and Magnetism

Front

What is a conductor?

Back

A conductor is a material that allows electric charges to flow through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric charges, such as rubber, glass, and plastic.

Front

What happens when like poles of magnets are brought close together?

Back

They will repel each other.

Front

What happens when opposite poles of magnets are brought close together?

Back

They will attract each other.

Front

What are electric field lines?

Back

Electric field lines are visual representations of electric fields, showing the direction of the force that a positive charge would experience.

Front

What direction do electric field lines point?

Back

Electric field lines point away from a positive charge and towards a negative charge.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by increasing the voltage of the battery or wrapping more coils around the core.

Front

What happens if an object accumulates negative charges?

Back

The object becomes negatively charged.

Front

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

Back

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