EMF, magnetic flux denisty and force. (1 Viewer)

Hi
What exactly is emf,

is this valid, by increasing the magnetic field strength the magnetic flux is increased hence the force acting on the coil is greater?

By increasing the magnetic field strength am I increasing the current flowing through the circuit?

Emf (electromotive force) basically = voltage.

When there is relative motion between a conductor and a magnetic field (either conductor moves, or magnetic field varies), an emf / voltage is induced in the conductor.

When a circuit is provided, a current flows in the conductor.

The induced emf / voltage / current depends on;

- Magnetic field strength (magnetic flux density).
- Rate of change of magnetic flux through the conductor / circuit (meaning if there is a sudden increase in flux lines through the conductor, a larger emf is induced).
- The number of conductors.

By increasing the magnetic field strength in which the conductor lies, there is a change in flux, and thus a greater induced current.
