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) positively charged alpha particles, (ii) neutrons? Justify your answer by giving suitable arguments.

Electric current is established due to the flow of electrons in a metallic conductor. Electrons are negatively charged particles.

(i) A magnetic field will be produced around a thin beam of positively charged alpha particles due to its charge.

(ii) No magnetic field will be produced around a thin beam of neutrons because neutrons have no charge on them.
