If an electron passes through the axis of the solenoid the movement will be:
Correct answer: D. No force acts on it
- A. Towards the outside
- B. Towards the inside
- C. Parallel to its motion
- D. No force acts on it
Explanation
The electron is moving along the axis with velocity VForce = q(V x B)Velocity and magnetic field are in the same direction or at an angle of 180V x B = VBsin(0 or 180) = 0Force = 0The image shows the direction of the magnetic field inside a solenoid.

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.
