the magnitude of force on a moving charge is not zero when the angle between the velocity of the charge carrier and the magnetic field is zero. The magnetic force on a charged particle is given by the following equation: F = qvB sin θ where: F is the magnetic force (N) q is the charge of the particle (C) v is the velocity of the particle (m/s) B is the magnetic field strength (T) θ is the angle between the direction of the velocity and the direction of the magnetic field (°) When the angle between the velocity and the magnetic field is zero, then the sine of the angle is also zero. sin 0° = 0 The magnetic force is then zero. Therefore, the magnitude of the force on a moving charge is not zero when the angle between the velocity of the charge carrier and the magnetic field is zero.

- B. 90o
- C. 45o
- D. 120o
Explanation
Option A is correct.The magnitude of force on a moving charge is zero when the angle between the velocity of the charge carrier and the magnetic field is zero. The magnetic force on a charged particle is given by the following equation: F = qvB sin θ where: θ is the angle between the direction of the velocity and the direction of the magnetic field (°) When the angle between the velocity and the magnetic field is zero, then the sine of the angle is also zero. sin 0° = 0 The magnetic force is then zero. Therefore, the magnitude of the force on a moving charge is zero when the angle between the velocity of the charge carrier and the magnetic field is zero.

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.
