Question
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
- alpha particles,
- neutrons? Justify your answer.
Solution
Magnetic field is produced by a current-carrying conductor due to the motion of charged particles or electrons.
- As alpha particles are positively charged and they constitute current in the direction of motion, so their movement will also produce a magnetic field.
- Neutrons do not carry any charge and constitute no current, so their motion will not produce any magnetic field
