repel

Repel means to push something away. In science, repel is often used to describe the force between two magnets. Opposite poles of magnets attract each other, while like poles repel each other. This is because magnets have two types of charges, called north and south poles. Opposite poles have different types of charges, so they attract each other. Like poles have the same type of charge, so they repel each other.

Here are some examples of how repel is used in science:

• Magnets repel each other when their north poles are facing each other.
• Water and oil repel each other because they have different types of molecules.
• Charged particles repel each other if they have the same charge.
