EMF Investigation 2

Front

What are magnetic domains?

Back

Magnetic domains are small regions within a magnet where the magnetic fields of atoms are aligned in the same direction.

Front

How do the magnetic domains of a magnet differ from those of an ordinary piece of metal?

Back

In a magnet, the domains all point in the same direction; in an ordinary piece of metal, they're all jumbled up.

Front

Which metal is commonly known to be magnetized?

Back

Iron is the metal that can be magnetized.

Front

What type of energy does an object have when it is not moving?

Back

Potential energy.

Front

What causes the magnetic domains of a paperclip to line up?

Back

The paperclip has been exposed to a magnetic field.

Front

What happens to kinetic energy when an object comes to a stop?

Back

Kinetic energy is converted to potential energy.

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

Can all metals be magnetized?

Back

No, only certain metals like iron can be magnetized.

Front

What is an electromagnet?

Back

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