Electromagnetic induction Michael Faraday was the first person to generate electricity from a magnetic field using electromagnetic induction. The large generators in power stations generate the electricity we need using this process. Current is created in a wire when: the wire is moved through a magnetic field ('cutting' the field lines)

An electromotive force (e.m.f.) is induced in a conductor whenever there is relative movement between the conductor and a magnetic field. This could be when. the conductor moves in a stationary magnetic field. the conductor is stationary in a changing magnetic field.

force in the track is created by a induced magnetic field in conductors within the tracks. Problems: at slow speeds the current induced in the coils of the track’s conductors and resultant magnetic flux is not large enough to support the weight of the train.
A circular loop having 5 turns undergoes a shift in its magnetic flux from +30 Wb to -40 Wb within a duration of 0.25 s in a uniform manner. Calculate the induced electromotive force.
A current is induced in a circular loop of radius 1.5 cm between two poles of a horseshoe electromagnet when the current in the electromagnet is varied. The magnetic field in the area of the loop is perpendicular to the area and has a uniform magnitude.
