then positive charge will be produced on
[ ]
a) Plate A
b) Plate B
S N
c) Neither on plate A nor on plate B
d) Either on plate A or on plate B
A B
.​

Answer 1

Answer:

N is the answer

Explanation:

pls mark as brainliest

Answer 2

Answer:

As, the magnet moves toward the coll,

flux linked with the coil increases,

hence according to the Lenz's law,

it will oppose the change.

Here, the north pole is approaching the magnet,

so the induced current in the face of the loop viewed

from left side will flow in such a way that it will behave

like North Pole,

so South pole developed in loop when viewed from right hand side

of the loop.

The flow of induced current is clockwise,

hence A acquires positive polarity and B negative.
