The right-hand palm rule is used to find the direction of:
Correct answer: B. Force
- A. Current
- B. Force
- C. EMF
- D. Temperature
Explanation
The right-hand palm rule is a mnemonic used to determine the direction of the magnetic force on a positive charge moving in a magnetic field. The fingers point in the direction of the magnetic field, the thumb points in the direction of the charge's velocity, and the force is directed out of the palm.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
