what causes electromagnetic induction?

how does magnetic flux linkage create an emf in a coil?

[DuaneM2631]

Moving a magnet across a conductor or a conductor moving across a magnet will induce a current which will in turn set up an emf based on the direction of the magnetic field.

[scibod2268]

It is the rate of change of the amount of flux linking with the coil that causes the emf (Faradays law). It arises because charged particles, usually electrons, experience a force when moving relative to a magnetic field. In a conductor this has the effect of moving them to one side of the conductor and so creating a difference in 'voltage' across it.
