An induced electromotive force in any closed circuit is equal to the negative of the time rate of change of the magnetic flux enclosed by the circuit.The shell – a bullet is held in an armature that can conduct electricity, which is then placed between two metal rails.
A huge electric current is then passed through the rails, which generates magnetic fields that propels the armature forwards at a great velocity, refer to figure. The shell when it detaches from the armature, can reach up to seven times the speed of sound.Electromagnetic induction is an incredibly useful phenomenon with a wide variety of applications. Faraday’s discovery of electromagnetic induction gives rise to countless technological industrial, technological, medical applications.
