The correct answer is: B. Magnetic flux, direction of motion and the direction of e.m.f. induced.
Fleming’s right-hand rule is a mnemonic device used to determine the direction of the induced current in a conductor when it is moving through a magnetic field. The rule states that if you point your thumb in the direction of the magnetic field, your index finger in the direction of the motion of the conductor, and your middle finger in the direction of the current, your fingers will form a right-hand screw. The direction of the current is the direction in which the screw would advance.
For example, if a conductor is moving to the right in a magnetic field that is pointing into the page, the induced current will flow in a counterclockwise direction.
The other options are incorrect because they do not accurately describe Fleming’s right-hand rule. Option A is incorrect because it includes the direction of current flow, which is not part of Fleming’s right-hand rule. Option C is incorrect because it includes the magnetic field strength, which is not relevant to the direction of the induced current. Option D is incorrect because it includes the direction of force, which is not relevant to the direction of the induced current.
