Across
- 2. The region of space surrounding a body in which another body experiences a force of gravitational attraction
- 4. A material that allows electrons to flow freely from particle to particle
- 5. The flow of an electric charge through an object or medium
- 6. A physical condition existing in space that causes particles placed within the space to experience a force
- 9. The production of electric potential difference across a conductor as the conductor moves through a magnetic field
- 11. The area around a magnet or moving electric charge that can exert a magnetic force
- 12. An electric current flowing in only one direction
- 14. An interaction between an object and another object or a field that acts to change the motion of the object
- 20. An electric current that reverses its direction many times a second at regular intervals
- 21. The SI unit of measurement for electric current
- 22. The SI unit for electromotive force, or the difference in potential that would drive one amp of current against one ohm of resistance
- 23. A law describing the electrostatic force of interaction between charged particles based on the strength of the charges and the distance between the particles
Down
