An electron beam produces

I) Electrical field around the beam

II) Magnetic field around the beam

III) Electrical field is more stronger than the magnetic field

IV) Electrical and Magnetic fields are not produced

Detailed Solution :

An electron beam produces both an electrical field and a magnetic field around it. These fields are fundamental properties of charged particles like electrons.
The electrical field around an electron beam is caused by the electric charge of the electrons in the beam. This field can affect nearby charged particles or objects and cause them to move or be attracted or repelled.

The magnetic field around an electron beam is caused by the movement of the charged particles in the beam. This field can affect nearby magnetic materials or conductive materials and cause currents to flow in them.
The strength of the electrical field and the magnetic field around an electron beam depends on various factors such as the velocity and the amount of charge of the electrons in the beam. However, in general, the electrical field is usually stronger than the magnetic field around an electron beam.

Hence, the correct option is C
