Question

A magnetic field, strength 3T, has a direction out of the page. A loop of wire sits in the field and on the plane of the page (area vector of loop is out of page). The loop is much smaller than the extent of the field. The magnetic field starts to slowly change at a rate of -0.0001T/s. Looking down on the loop, which statement is correct?

Magnetic flux out of page increasing; clockwise current induced in loop

Magnetic flux out of page decreasing; anti-clockwise current induced in loop

Magnetic flux out of page increasing; anti-clockwise current induced in loop

Magnetic flux out of page decreasing; clockwise current induced in loop

Magnetic flux out of page increasing; clockwise current induced in loop

Magnetic flux out of page decreasing; anti-clockwise current induced in loop

Magnetic flux out of page increasing; anti-clockwise current induced in loop

Magnetic flux out of page decreasing; clockwise current induced in loop

Explanation / Answer

because our magnetic field is decreasing with tiem so loop will produce a current in a direction to decreas total magnetic field ( by lenz's law )

Magnetic flux out of page decreasing; anti-clockwise current induced in loop

Magnetic flux out of page decreasing; anti-clockwise current induced in loop
