Electricity and Magnetism Flashcard

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It typically consists of a coil of wire wrapped around a core material, such as iron.

Front

How can you make an electromagnet stronger?

Back

You can make an electromagnet stronger by adding more coils of wire to the core or increasing the electric current flowing through the wire.

What happens to opposite charges when they interact?

Back

Opposite charges attract each other.

Front

What happens to like charges when they interact?

Back

Like charges repel each other.

Front

What is the negatively charged particle in an atom?

Back

The negatively charged particle in an atom is called an electron.

Front

What is the symbol for a battery in circuit diagrams?

Back

The symbol for a battery is two parallel lines, one longer than the other.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which the components are connected across common points or junctions, allowing multiple paths for the current to flow.

Front

What is a resistor?

Back

A resistor is a component in an electrical circuit that resists the flow of electric current, creating a voltage drop.

Front

What is the function of a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.
