It is established that an electric current through a conductor produces a magnetic field arount 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 .
Text Solution
Verified by Experts
In case of movement of a charged particle , the magnetic field is created around the path on which charged particle moves . (i) Alpha particles being positively charged constitute a current in the direction of motion , therefore magnetic field will be produced around a thin beam of moving alpha particles. (ii) The neutrons being electrically neutral constitute no current , so no magnetic field will be produced around a thin beam of moving neutrons .
