It is established that an electric current through a 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 in each case.
(1) Alpha particles have electric charge by which they can produce magnetic field, and these particles electric charge is equal to 2 electrons.
(2) Neutron can not produce a magnetic field because they have no charge in them.
