Electricity and Magnetism Flashcard #2

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.

How can you make an electromagnet stronger?

Back

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

Front

What happens when you reverse the poles of a magnet?

Back

When you reverse the poles of a magnet, the direction of the magnetic field changes, which can affect how it interacts with other magnets or magnetic materials.

Front

What type of energy does a generator produce?

Back

A generator produces electrical energy from mechanical energy.

Front

What is a magnetic field?

Back

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

Front

What is the difference between attraction and repulsion in magnets?

Back

Attraction occurs when opposite poles of magnets (north and south) come together, while repulsion occurs when like poles (north-north or south-south) push away from each other.

Front

What is the role of a switch in an electrical circuit?

Back

A switch controls the flow of electricity in a circuit. When the switch is closed, electricity flows; when it is open, the flow is interrupted.

Front

What materials can be used to make a magnet?

Back

Materials that can be magnetized include iron, nickel, cobalt, and some alloys. These materials have magnetic domains that can align to create a magnetic field.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, which can cause them to attract or repel each other.

Front

How do magnets interact with each other?

Back

Magnets interact through their magnetic fields, attracting or repelling each other depending on the orientation of their poles.
