Magnets & Static Electricity

Front

What is a neodymium magnet?

Back

A neodymium magnet is a type of rare-earth magnet made from an alloy of neodymium, iron, and boron, known for its strong magnetic properties.

Front

What is the force called when two magnets repel each other?

Back

The force is called repulsion.

Front

What materials are typically attracted to magnets?

Back

Materials that are typically attracted to magnets include ferromagnetic materials such as iron, nickel, and cobalt.

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

What happens when you bring two like poles of magnets together?

Back

When two like poles of magnets (e.g., north-north or south-south) are brought together, they repel each other.

Front

What is the difference between permanent magnets and temporary magnets?

Back

Permanent magnets maintain their magnetism over time, while temporary magnets only exhibit magnetic properties when in the presence of a magnetic field.

Front

What is the role of aluminum in relation to magnets?

Back

Aluminum is a non-magnetic material, meaning it does not stick to magnets.

Front

What are some common applications of electromagnets?

Back

Common applications of electromagnets include electric motors, generators, magnetic locks, and MRI machines.

Front

What is magnetic field strength?

Back

Magnetic field strength is a measure of the intensity of the magnetic field produced by a magnet, typically measured in teslas (T) or gauss (G).

Front

What is the principle of magnetic induction?

Back

Magnetic induction is the process by which a material becomes magnetized when exposed to a magnetic field.
