Force Acting on a Coil in a Magnetic Field
Physics: AQA GCSE Higher, topic 7.2.11
Force Acting on a Coil in a Magnetic Field
In a magnetic field, a coil of wire carrying a current experiences forces that make it rotate about its axis. To increase the force acting on the coil:
More turns on the coil
- Increasing the number of turns on the coil increases the size of the turning force.
Higher current
- Increasing the current through the coil increases the size of the turning force.
Magnetic field strength
- Increasing the strength of the magnetic field increases the size of the turning force.
