Question: A loop of wire is placed in a uniform magnetic field. If the magnetic field is increased uniformly, what happens to the induced current in the loop?

Options:

It increases
It decreases
It remains constant
It becomes zero

Correct Answer: It increases

Solution:

According to Faraday\'s law, an increase in magnetic field through the loop induces a current in the loop, which increases as the rate of change of magnetic flux increases.

Questions & Step-by-Step Solutions

A loop of wire is placed in a uniform magnetic field. If the magnetic field is increased uniformly, what happens to the induced current in the loop?

Step 1: Understand that a loop of wire can have a current induced in it when it is in a magnetic field.
Step 2: Know that a magnetic field is a region where magnetic forces can be felt.
Step 3: Recognize that when the strength of the magnetic field increases, it affects the magnetic flux through the loop.
Step 4: Remember that magnetic flux is the amount of magnetic field passing through the loop.
Step 5: According to Faraday's law, a change in magnetic flux through the loop induces an electric current.
Step 6: Since the magnetic field is increasing uniformly, the magnetic flux is also increasing.
Step 7: As the magnetic flux increases, the induced current in the loop also increases.
Step 8: Conclude that the induced current will continue to increase as long as the magnetic field keeps increasing.

Faraday's Law of Electromagnetic Induction – This law states that a change in magnetic flux through a loop induces an electromotive force (EMF) in the loop, which can cause a current to flow.
Magnetic Flux – Magnetic flux is the product of the magnetic field strength and the area of the loop perpendicular to the field, and it is crucial for understanding how changes in the magnetic field affect induced current.
Induced Current – The current that flows in the loop as a result of the induced EMF due to the changing magnetic field.
