Question

When an electron moves through a uniform magnetic field, what factors determine the magnitude and direction of the magnetic force acting on it?

Answer 1

The magnitude and direction of the magnetic force acting on an electron moving through a uniform magnetic field are determined by the magnitude of the charge, velocity, magnetic field, and angle between the velocity and magnetic field vectors.

Step-by-step explanation:

The magnitude and direction of the magnetic force acting on an electron moving through a uniform magnetic field is determined by several factors:

1. Magnitude of the charge: The magnetic force is proportional to the magnitude of the charge on the electron. A larger charge will experience a stronger magnetic force.
2. Magnitude of the velocity: The magnetic force is also proportional to the magnitude of the velocity of the electron. A higher velocity will result in a stronger magnetic force.
3. Magnitude of the magnetic field: The magnetic force is directly proportional to the magnitude of the magnetic field. A stronger magnetic field will exert a stronger force on the electron.
4. Angle between the velocity and magnetic field vectors: The magnetic force depends on the angle between the velocity of the electron and the magnetic field. The force is maximum when the velocity and magnetic field vectors are perpendicular (90 degrees).
