Question

In the figure, a region with constant (externally produced) magnetic field is shown. A wire loop moves into the magnetic field. Which of the following is correct? While the loop is moving into the region with the constant external magnetic field, the magnetic field inside the loop due to the induced current in the loop points... ..into the page ..out of the page ..left ..up No magnetic field is induced by the movement of the loop. ..down ..right which at the following is correct? While the loop is moving into the region with the constant external magnetic field, the magnetic force on the loop points... out of the page .. up ..into the page ..right ..left There is no magnetic force acting on the loop. ..down

Explanation / Answer

Concept used : lenz's Law and flemings left hand rule.

Q1. This involves lenz's law

The flux through loop is increasing outwards so current induced in loop will such that it will oppose this increase in flux(current will be clockwise) so field generated by this current will be into the page.

Q2.This involves flemings left hand rule

As current induced in loop is in clockwise direction and field is in outward direction so as per flemings left hand rule force on loop will be towards right.
