The magnitude of the induced electromotive force (emf) in a coil of wire is affected by four main factors: the strength of the magnetic field, the area of the coil, the number of turns in the coil, and the rate of change of the magnetic field. According to Faraday's law of electromagnetic induction, a stronger magnetic field or a larger coil area increases the induced emf. Additionally, more turns in the coil enhance the induced voltage, while a faster change in the magnetic field also contributes to a greater induced emf.
