Use this stack to review magnetism, electromagnets, and circuits
| Question | Answer |
|---|---|
| ___________ is the force of attraction or repulsion of magnetic materials. | magnetism |
| When like poles of two magnets are close together, they will ___________. | repel |
| Where is the magnetic field on a magnet the strongest? | poles |
| What device has the power to control whether a circuit is on or off? | switch |
| A material that allows heat energy or electricity to pass through easily. | conductor |
| The magnetic field around a wire forms what shape? | circle |
| The area where a magnetic force can be detected. | magnetic field |
| A coil of wire with a iron core and acts as a magnet when an electric current is in the coil. | electromagnet |
| Magnetism is a type of | force |
| Opposite poles (north/south) of a magnet _______ each other. | attract |
| Like poles (north/north or south/south) of a magnet _________each other. | repel |
| The flow of an electric charge. | electric current |
| Materials that do not carry the current very well. | Insulators |
| The push the battery gives to the charge. | voltage |
| An incomplete path which a current cannot flow. | open circuit |
| In this circuit the current flows through a single loop. | series circuit |
| In this circuit the electric current can follow more than one path. | parallel |
| A map of a circuit | circuit diagram |
| Very strong temporary magnets that can be turned on and off. | electromagnet |
| Uses magnets and loops of wire to make electricty. | generator |
