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

(i) alpha- particles
(ii) neutrons? Justify your answer.

Answer 1

In case of movement of a charge particle, the magnetic field is created arround the path on which the charged particle moves.

$(i)$
Yes,
$a \: thin \: beam \: of \: \alpha - particles(which \: are \: positively \: charged \: ) \:is \: like \: straight \: conductor \: carrying \: current \: in \: the \: direction \: of \: motion.$
(ii)
No, as neutrons carry zero charge, so no magnetic field would be produced around its path.
