Assertion : It is more difficult to push...

Assertion : It is more difficult to push a magnet into a coil with more loops.
Reason : Emf induced in the current loop resists the motion oif the magnet.

Text Solution

Verified by Experts

The correct Answer is:
a
According to Lenz's law, the emf induced in a current loop is such that it resists the motion of the magnet. As emf in each turn opposes the motion of the magnet, when the number of turns is increases the force opposing the motion also increases. Thus pushing a magnet into a coil with more number of loops is more difficult.

PQRS is a square region of side 2a in the plane of paper. A uniform magnetic field B, directed perpendicular to the plane of paper and into its plane is confined within this square region. A square loop of side 'a' and made of a conducting wire of resistance R is moved at a constant velocity vec(v) from left to right in the plane of paper as shown. Obviously, the square loop will enter the magnetic field at some time and then leave it after some time. During the motion of loop, whenever magnetic flux through it changes, emf will be induced resulting in induced current. Let the motion of the square loop be along x-axis and let us measure x coordinate of the centre of square loop from the centre of the square magnetic field region (taken as origin). Thus, x coordinate will be positive if the centre of square loop is to the right of the origin O (centre of magnetic field) and negative if centre is to the left. For x = a//4 (i) magnetic flux through the loop, (ii) induced current in the loop and (iii) external force required to maintain constant velocity of the loop, will be

Assertion If a magnet is brought closer to a current carrying loop along its axis, then current always decreases in the loop. Reason Magnet is repelled by the loop.
