Question

A conductor depicted as AB is moving towards you, out of the plane, with two magnets kept as shown below(the magnetic field is from left to right). What is the direction of induced current?

• A. from B to A
• B. from A to B
• C. Current is not induced
• D. cannot be determined

Answer 1

The correct option is A

from B to A

Using Fleming’s right-hand rule, we find that when the conductor is moving towards you, the thumb is taken towards yourself.
Now, when the magnetic field is taken from left to right, the current is in an upward direction, or in other words, from B to A. Hence, the current will flow horizontally right from A and downward in the right wire. Hence, the deflection in the galvanometer will be downwards.
