When a conductor is cut by 2 webers of flux lines in 1 second, what is the induced voltage?

The induced voltage in a conductor due to a changing magnetic flux is determined by Faraday's law of electromagnetic induction. According to this principle, the induced voltage (or electromotive force, EMF) in a closed loop is equal to the rate of change of magnetic flux through that loop.

In this scenario, if a conductor is cut by 2 webers of magnetic flux in 1 second, the formula for induced voltage can be expressed as:

Induced Voltage (V) = Change in Magnetic Flux (Φ) / Time (t)

Substituting the values provided:

V = 2 webers / 1 second = 2 volts

Thus, the induced voltage is correctly evaluated to be 2 volts because it directly follows from the fundamental principles of electromagnetic induction. The rate of change of the magnetic flux through the conductor determines how much voltage is induced, and in this case, the effective change in magnetic flux is 2 webers within a one-second interval, leading to an induced voltage of 2 volts.
