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

Correct answer: A. Parallel to magnetic field

  • A. Parallel to magnetic field
  • B. Both option A and C
  • C. Perpendicular to magnetic field
  • D. None of these

Explanation

The magnetic force experienced by a charged particle moving in a magnetic field is given by the equation:\[ F = q \cdot v \cdot B \cdot \sin \theta \]where:- \( F \) is the magnetic force,- \( q \) is the charge of the particle,- \( v \) is the velocity of the particle,- \( B \) is the magnetic field strength,- \( \theta \) is the angle between the velocity vector and the magnetic field vector.When the charged particle moves parallel to the magnetic field lines, the angle \( \theta \) is 0 degrees. In trigonometry, \(\sin 0^\circ\) is equal to 0. Therefore, the term \(\sin \theta\) becomes 0, resulting in the magnetic force \( F = 0 \). This means that the force experienced by the charged particle is at its minimum when it moves parallel to the 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.
