Using Fleming’s right-hand rule, in which direction will the current flow if the direction of magnetic field is towards north and the conductor is moving vertically upward?

Correct option is B

The correct answer is (b) towards west.
Fleming’s right-hand rule is used to determine the direction of induced current in a conductor moving within a magnetic field. According to this rule, if you extend your right hand with the thumb, forefinger, and middle finger perpendicular to each other:
· The thumb represents the direction of motion of the conductor (force).
· The forefinger indicates the direction of the magnetic field.
· The middle finger shows the direction of the induced current.
In this question:
· The magnetic field is directed towards north (indicated by the forefinger).
· The conductor is moving upward (represented by the thumb).
By aligning your hand according to these directions, the middle finger will point towards west, which is the direction of the induced current.

Additional Information:
· Fleming's right-hand rule is a fundamental concept in electromagnetism, particularly for understanding electromagnetic induction, where a moving conductor in a magnetic field generates an electric current.
· This rule is primarily used in generators to predict the direction of current flow in the generator’s coil as it rotates in a magnetic field.
