Bar Magnets Electromagnets Bar Magnets and Electromagnets
Bar Magnets:
- Made of a solid piece of magnetic material
- Has a north and south pole
- Magnetism is constant and cannot be turned on or off
- Magnetic field produced is relatively weak
Electromagnets:
- Created by passing an electric current through a wire coil
- Can be turned on and off by controlling the electric current
- Strength of the magnetic field can be adjusted by changing the amount of current flowing through the coil
- Can be made stronger than bar magnets by using a stronger current or more turns in the coil
Bar Magnets and Electromagnets:
- Used in various applications such as generators, motors, and speakers
