What term describes the voltage generated when a wire or coil cuts across the lines of a magnetic field?

The term that describes the voltage generated when a wire or coil cuts across the lines of a magnetic field is referred to as "induced voltage." This phenomenon is a direct result of electromagnetic induction, which occurs when a conductor moves through a magnetic field or when the magnetic field around a conductor changes. According to Faraday's Law of Electromagnetic Induction, the magnitude of the induced voltage is proportional to the rate at which the magnetic field lines are cut.

While "induced current" refers to the flow of electric charge that is generated as a result of the induced voltage, it is the voltage itself that is being directly described. "Induced potential difference" essentially conveys a similar idea, as potential difference is a synonym for voltage, but the more common term used in this context is "induced voltage." "Magnetic flux," on the other hand, refers to the measure of the quantity of magnetism, taking into account the strength and the extent of a magnetic field, and is not directly related to the voltage generated by cutting through field lines. Therefore, the correct term is "induced voltage," as it accurately describes the electrical property generated by the interaction of the conductor with the magnetic field.
