MAGNETISM Flashcards
1
Q
- one of the strongest naturally working
- oxide of iron (Fe304)
- Lodestone/ Leading Stone
A
Magnetite
2
Q
- a property created when electrons behave as if they rotate on its axis
- is neutralized in electron pairs
- unlike poles does not contribute that much of like poles
- lines of a magnetic field are always closed loop
A
Electron Spin
3
Q
- a nuclear magnetic dipole created when a magnetic field is created by a spinning electric charge
A
Magnetic Moment
