Question: What happens to the induced EMF if the area of the coil is increased while the magnetic field strength remains constant?

Options:

It increases
It decreases
It remains the same
It becomes zero

Correct Answer: It increases

Solution:

Increasing the area of the coil while keeping the magnetic field strength constant increases the magnetic flux through the coil, which according to Faraday\'s law increases the induced EMF.

Questions & Step-by-Step Solutions

What happens to the induced EMF if the area of the coil is increased while the magnetic field strength remains constant?

Step 1: Understand what EMF is. EMF stands for electromotive force, which is the voltage generated by a coil in a magnetic field.
Step 2: Know what a coil is. A coil is a loop of wire that can generate electricity when it interacts with a magnetic field.
Step 3: Recognize what magnetic field strength means. Magnetic field strength is how strong the magnetic field is around the coil.
Step 4: Learn about area of the coil. The area of the coil is the size of the loop of wire. A larger area means more space for the magnetic field to pass through.
Step 5: Understand magnetic flux. Magnetic flux is the amount of magnetic field passing through the area of the coil. It depends on both the strength of the magnetic field and the area of the coil.
Step 6: Realize the relationship between area and magnetic flux. If you increase the area of the coil while keeping the magnetic field strength the same, the magnetic flux through the coil increases.
Step 7: Apply Faraday's law. Faraday's law states that the induced EMF in a coil is directly proportional to the rate of change of magnetic flux through the coil.
Step 8: Conclude that increasing the area increases the magnetic flux, which leads to an increase in the induced EMF.

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