A magnetic field acts on a charged particle so as to change its:

Correct answer: B. Direction of motion

  • A. Speed C .
  • B. Direction of motion
  • C. Energy
  • D. All of these

Explanation

Magnetic force is simply a deflecting force. It will change the direction of charge particle moving in magnetic field. So, only direction of motion will change not magnitude.

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.
