Magnetic Fields
| Question | Answer |
|---|---|
| What does attract mean? | To pull towards one another. |
| What word means to push objects away from each other? | Repel |
| What is a magnetic field? | The space around a magnet in which magnetic forces can act on objects. |
| What is a magnetic pole? | One of the two opposite ends of a magnet. |
| Fill in the blank: ____________ poles repel. | Same or like poles |
| Fill in the blank: ____________ poles attract. | Opposite poles |
| Using the magnetic field lines, how can you tell if two magnets will repel or attract? | If their field lines connect to their own magnet, it will repel. If it connects to the other magnet it will attract. |
| How do magnets move objects? | They can attract or repel some objects using a MAGNETIC FORCE. |
| Where is potential energy stored in a system of magnets? | In the magnetic field. |
| Is one magnet a system? | No, you need two magnets for a system. |
