According to Fleming’s right-hand rule, the stretched middle finger indicates the direction of the induced current. This rule is used to determine the relationship between a magnetic field, a current-carrying conductor, and the resulting force acting on the conductor.

To apply the rule, we place our right hand with the thumb, forefinger, and middle finger at right angles to each other. The forefinger represents the direction of the magnetic field, and the thumb represents the direction of motion of the conductor.

The stretched middle finger, in this case, represents the direction of the induced current. An induced current is created when a conductor moves through a magnetic field or when there is a change in the magnetic field through a conductor. This induced current, according to Fleming’s right-hand rule, will flow in a direction perpendicular to both the magnetic field and the motion of the conductor.

The other options can be eliminated because they are not predicted by Fleming’s right-hand rule. The force acting on the conductor (option 1) is not determined by the stretched middle finger in this rule. The electric field (option 2) and current (option 4) are also not directly determined by this rule.

Therefore, the correct answer is option 3, which predicts the direction of
