The term 'Magnetic Pole' refers to:

• The region at each end of a magnet where the magnetic force is strongest.

• The center point of a magnet where no force is present.

• A point where electricity is generated in a magnet.

• The area around a magnet where gravity is strongest.

A magnetic field is best described as:

• A region around a magnet where magnetic forces can be detected.

• A type of electric current flowing through a wire.

• A field that only exists inside magnets and not around them.

• A force that only affects non-metallic objects.

The two types of electric charge and their interaction with each other are:

• Positive and negative; like charges repel and unlike charges attract each other.

• Positive and neutral; all charges attract each other.

• Negative and neutral; like charges attract and unlike charges repel each other.

• Positive and negative; like charges attract and unlike charges repel each other.

When you rub a balloon on your hair, what happens in terms of electrons, charge, and electric force?

• Electrons move from your hair to the balloon, giving the balloon a negative charge and creating an electric force.

• Electrons move from the balloon to your hair, giving the balloon a positive charge and creating an electric force.

• Protons move from your hair to the balloon, giving the balloon a negative charge and creating an electric force.

• Neutrons move from your hair to the balloon, giving the balloon a negative charge and creating an electric force.
