☜☆☞ There should be an suitable environment to be set up in order to induce the current in the coil. The concept lies in the changing of flux through the coil, this will induce an emf and current starts flowing. Now changing of flux can be one in two ways.
Either you move the coil in the constant magnetic field, this will change the number of magnetic field line passing through the coil.
By establishing an alternating magnetic flux, this can be done by periodic reversal of the direction of the current in the source which is generating the magnetic field. In this way flux will also change according to change in current and ultimately the flux line to the conductor will also change.
In both the way the current induced will try to oppose the cause, in other words the induced current will in turn set up a magnetic field will be repelling to that of the source.
Magnetic field is actually a force which aligns the electrons of the conductor in specific direction and induces dipole. So electrons start moving in the specific direction and thus how current is induced.

======================================
⊙A strong magnetic field through a coil a wire therefore must induce an emf in the coil which in turn causes current to flow.
⊙The law describing induced emf is named after the British scientist Micheal Faraday but Faraday law should really be called as Henry law that determines the induced current.
