Question

A loop rests in the plane of a page of textbook while a magnetic field is directed into the page. A clockwise current is induced Check all that apply. when the magnetic field is tilted so it is no longer perpendicular to the page. when the magnetic field gets stronger. when the loop is moved sideways across the page. when the size of the loop decreases.

Answer 1

Answer:

When the magnetic field is tilted so it is no longer perpendicular to the page.

When the magnetic field gets stronger.

When the size of the loop decreases.

Explanation:

According to the Faraday-Lenz law, the change of the magnetic flux over time causes an induced current, this flux is given by:

$\Phi_B=BScos\theta$

Therefore, there will be a variable magnetic flux, when the magnitude of the magnetic field (B) changes over time, when the area of the loop (S) changes over time and / or when the angle ($\theta$) between the field and the surface vector changes over time.
