PHY 102 Electromagnetic Induction 2 Objective Question

Question

In Fleming's Right Hand Rule, if the forefinger represents the direction of the line of force and the thumb points in the direction of motion or applied force, what does the second finger represent?
Options
A The direction of the magnetic field strength (B).
B The direction of the induced current.
Correct Answer
C The direction of the electromotive force (EMF).
D The magnitude of the applied force.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 21 explicitly states: 'Hold out the right hand with the first finger, second finger and thumb at the right angle to each other. If forefinger represents the direction of the line of force, the thumb points in the direction of motion or applied force, then second finger points in the direction of the induced current'.

Hint

Fleming's Right Hand Rule is often called the 'Generator Rule' because it helps determine the direction of induced current.
