Question

A circular loop lies in the plane of the screen. There is an initial magnetic field pointing toward you of strength B(initial). The field is changed in a short time so that the final magnetic field is the same strength but now pointing into the page. During this process, which is the best description of the directions for the Induced B field and the direction of the induced EMF respectively. up toward the top of the page, into the page Into the page, out of the page to the right, cw up toward the top of the page, out of the page to the right, ccw Into the page, into the page out of the page, cw out of the page, CCW

Answer 1

This problem is from topic elwctromagnetic induction.

According to Lenzs law emf is induced in such a direction so that induced emf opposes change in magnetic flux through coil.Here magnetic flux in direction out of page is decreasing.

So correct option is : Out of page ,ccw.
