Question: If the magnetic field through a loop is increased uniformly, what happens to the induced current in the loop?

Options:

Correct Answer: It flows in the opposite direction to the magnetic field

Solution:

According to Lenz\'s law, the induced current will flow in the opposite direction to oppose the increase in magnetic flux.

If the magnetic field through a loop is increased uniformly, what happens to the induced current in the loop?

Step 1: Understand that a loop of wire can have a magnetic field passing through it.
Step 2: Recognize that when the magnetic field through the loop increases, it changes the magnetic flux (the amount of magnetic field passing through the loop).
Step 3: Remember Lenz's law, which states that the induced current will flow in a direction that opposes the change in magnetic flux.
Step 4: Since the magnetic field is increasing, the induced current will flow in a direction that creates a magnetic field opposing the increase.
Step 5: Conclude that the induced current will flow in the opposite direction to the increase in the magnetic field.

Electromagnetic Induction – The process by which a changing magnetic field induces an electromotive force (EMF) and consequently a current in a conductor.
Lenz's Law – A principle stating that the direction of induced current is such that it opposes the change in magnetic flux that produced it.
