Question: What happens to the induced EMF if the speed of a conductor moving through a magnetic field is doubled?

Options:

Correct Answer: It doubles

Solution:

If the speed of the conductor is doubled, the rate of change of magnetic flux increases, thus the induced EMF also doubles.

What happens to the induced EMF if the speed of a conductor moving through a magnetic field is doubled?

Step 1: Understand that EMF (Electromotive Force) is induced when a conductor moves through a magnetic field.
Step 2: Know that the induced EMF depends on the speed of the conductor moving through the magnetic field.
Step 3: If the speed of the conductor is doubled, it means the conductor is moving faster through the magnetic field.
Step 4: When the speed increases, the rate at which the magnetic field lines are cut by the conductor also increases.
Step 5: Since the rate of change of magnetic flux increases, the induced EMF will also increase.
Step 6: Specifically, if the speed is doubled, the induced EMF will also double.

Faraday's Law of Electromagnetic Induction – The induced EMF in a circuit is directly proportional to the rate of change of magnetic flux through the circuit.
Motion in a Magnetic Field – The motion of a conductor through a magnetic field induces an EMF based on the speed of the conductor.
