alleryFLEMING'S LEFT-HAND RULE relates which three quantities mutually perpendicular?
AVelocity, charge, and electric field strength
BForce, current, and magnetic field direction
CMass, acceleration, and gravitational field
DPressure, volume, and temperature of gases
Answer & Solution
Correct answer: B. Force, current, and magnetic field direction
**Fleming's Left-Hand Rule:** stretch left hand so thumb, forefinger, and middle finger are mutually perpendicular.
FOREFINGER = Magnetic Field, MIDDLE finger = Current, THUMB = Force (motion).
