Question: A coil of wire is placed in a magnetic field. If the magnetic field strength is doubled, what happens to the induced EMF?

Options:

Correct Answer: It doubles

Solution:

Doubling the magnetic field strength will double the induced EMF, as it is directly proportional to the magnetic field strength.

A coil of wire is placed in a magnetic field. If the magnetic field strength is doubled, what happens to the induced EMF?

Correct Answer: Induced EMF will also double.

Step 1: Understand that a coil of wire in a magnetic field can have an induced EMF (electromotive force) when the magnetic field changes.
Step 2: Know that the induced EMF is directly related to the strength of the magnetic field.
Step 3: If the magnetic field strength is doubled, it means the strength is increased two times.
Step 4: Since the induced EMF is directly proportional to the magnetic field strength, doubling the magnetic field will also double the induced EMF.
Step 5: Therefore, if the magnetic field strength is doubled, the induced EMF will also be doubled.

Faraday's Law of Electromagnetic Induction – The induced EMF in a coil is directly proportional to the rate of change of magnetic flux through the coil, which includes the strength of the magnetic field.
Magnetic Flux – Magnetic flux is the product of the magnetic field strength and the area through which it passes, influencing the induced EMF.
