It is established that an electric current through a metallic conductor produces a magnetic field around it. Is there a similar magnetic field produced around a thin beam of moving (i) alpha particles, (ii) neutrons? Justify your answer.

Explanation

To determine whether a magnetic field is produced around a thin beam of moving alpha particles and neutrons, we can analyze each case step by step.

### Step-by-Step Solution:

1. **Understanding Electric Current and Magnetic Fields**:
- An electric current through a metallic conductor produces a magnetic field around it. This is a fundamental principle in electromagnetism.
- The direction of the magnetic field can be determined using the right-hand thumb rule, where the thumb points in the direction of the current, and the fingers curl in the direction of the magnetic field lines.
