Electricity may be generated by rotating a loop of wire between the poles of a magnet. The induced current is greates when:

a.Plane of loop makes an angle 45 degrees with the magnetic field
b.The plane of the loop is parallel to the magnetic field
c.The plane of the loop is perpendicular to the magnetic field
d.Magnetic flux through the loop is minimum.
.
I thought it would be parallel because it can't be perpendicular unless it is passing through the field. Magnetic flux through loop would have to be maximum not minimum but I'm not sure about the 45 degree angle.

c is the anwswer.

My teacher told me it isn't perpendicular because it is not passing through but rotating so now I'm totally confused-Could you please look at this again?

Thank you

Could you please recheck this above-because my teacher said perpendicular isn't correct

To determine in which scenario the induced current is greatest, we need to consider Faraday's law of electromagnetic induction. According to this law, the magnitude of the induced electromotive force (emf) is directly proportional to the rate of change of magnetic flux through the loop.

Magnetic flux (Φ) is the product of the magnetic field strength (B) and the area (A) through which the magnetic field lines pass:

Φ = B * A

When the loop of wire is rotated between the poles of a magnet, the magnetic flux through the loop changes. Let's consider the given options one by one:

a. Plane of the loop makes an angle 45 degrees with the magnetic field:
In this scenario, the angle between the loop's plane and the magnetic field is 45 degrees. As a result, the effective area of the loop that is perpendicular to the magnetic field decreases, reducing the magnetic flux. Therefore, the induced current would be less in this case compared to when the plane of the loop is parallel or perpendicular to the magnetic field.

b. The plane of the loop is parallel to the magnetic field:
When the loop's plane is parallel to the magnetic field, the maximum possible area of the loop is exposed to the field lines, resulting in the maximum magnetic flux through the loop. Consequently, the induced current is greatest when the plane of the loop is parallel to the magnetic field.

c. The plane of the loop is perpendicular to the magnetic field:
When the loop's plane is perpendicular to the magnetic field, no magnetic field lines pass through the loop's area, resulting in zero magnetic flux. Therefore, no induced current is generated when the loop is in this position.

d. Magnetic flux through the loop is minimum:
If the magnetic flux through the loop is at a minimum, it means the magnetic field lines passing through the loop are also at a minimum. Consequently, the induced current would also be at a minimum.

Thus, the correct answer is option b. The plane of the loop should be parallel to the magnetic field to generate the greatest induced current.
