A strong magnetic field is applied to a stationary electron. Then the electron
Correct answer: C. starts spinning
- A. moves in the direction of the field
- B. moves opposite to the field
- C. starts spinning
- D. remains stationary
Explanation
C is the correct answer. In a strong magnetic field, a stationary charged particle, such as an electron, experiences a magnetic force perpendicular to both its velocity and the magnetic field direction. The magnetic force causes the electron to move in a circular or helical path, which can be interpreted as the electron "spinning" around the magnetic field lines.

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.
