The magnetic force experienced by a charge particle moving in a magnetic field will be minimum when it moves

Correct answer: B. Parallel to the field

  • A. Perpendicular to the field
  • B. Parallel to the field
  • C. Inclined at some angle to the field
  • D. Inclined at an angle of 45⁰

Explanation

Determining the Magnetic Force on a Charged Particle in Different Orientations to the Magnetic FieldWhen a charged particle moves parallel to the magnetic field, the angle between the velocity and the field is 0 degrees (\( \theta = 0^\circ \)). According to the formula \( F = qvB \sin(\theta) \), at \( \theta = 0^\circ \), the sine of \( \theta \) is also 0, resulting in zero force. Therefore, the force experienced when moving parallel to the field is minimum.### Correct Answer:When a charged particle moves parallel to the magnetic field, it experiences the minimum magnetic force according to the formula \( F = qvB \sin(\theta) \) due to \( \sin(0^\circ) = 0 \).

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.
