Fleming's left-hand rule applies to
AThe force on a current carrier in a magnetic field
BThe voltage induced in a moving coil only
CThe pressure of a gas in a closed pipe
DThe reflection of light by a plane mirror
Answer & Solution
Correct answer: A. The force on a current carrier in a magnetic field
1. The chapter introduces Fleming's left-hand rule.
2. Thumb, fore-finger and middle finger of the left hand show force, field and current respectively.
3. It predicts the direction of the force on a current in a field.
4. So option A is correct.
