When the direction of motion of a charged particle is perpendicular to the direction of magnetic field, then the particle follows the path of a:
Correct answer: D. Circle
- A. Straight line
- B. Ellipse
- C. Helix
- D. Circle
Explanation
When a charged particle moves perpendicular to a magnetic field, it experiences a force called the magnetic Lorentz force. This force acts as a centripetal force, causing the charged particle to move in a circular path. The resulting motion is circular because the force is always directed towards the center of the circle. This circular motion is often referred to as "circular motion in a magnetic field."

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.
