The force on a charged particle moving parallel to the magnetic field is:
Correct answer: B. Zero
- A. Maximum
- B. Zero
- C. Minimum
- D. None of these
Explanation
The force on a charged particle moving parallel to a magnetic field is zero.When a charged particle moves parallel to the magnetic field lines (i.e., the velocity vector is parallel to the magnetic field vector), the angle (θ) between the velocity vector (v) and the magnetic field vector (B) is 0 degrees. In this scenario, the force experienced by the charged particle can be calculated using the formula for the magnetic force:F = |q| * v * B * sin(θ)Since sin(0°) = 0, the force (F) becomes:F = |q| * v * B * 0 = 0Therefore, the force on the charged particle is zero. This means that a charged particle moving parallel to the magnetic field will not experience any magnetic force and will continue to move along its original path with a constant velocity.

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.
