Answer Details
Lenz's law of electromagnetic induction is a fundamental law in physics that describes the relationship between the change in magnetic flux and the induced electromotive force (EMF) and current. The law states that when there is a change in the magnetic flux through a closed loop, an EMF is induced in the loop that is proportional to the rate of change of the flux.
Furthermore, the direction of the induced EMF is such that it opposes the change that produced it. In other words, the induced current flows in a direction that creates a magnetic field that opposes the change in the original magnetic field.
This means that if the magnetic flux through a circuit increases, the induced current will create a magnetic field that opposes the increase in flux. Similarly, if the flux through the circuit decreases, the induced current will create a magnetic field that opposes the decrease in flux.
Therefore, among the given options, the correct answer is (B) the induced current in a conductor is in such a direction as to oppose the change producing it.
