Question

With thd help of a labelled circuit diagram wire describe an activity to illustrate the pattern of the magnetic field lines around a straight current carrying long conducting wire Is there a similar magnetic field produced around a thin beam of moving alpha particles and neutrons

Answer 1

just pass a straight conductor vertically through a table top....sprinkle iron filings on table pass current through the conductor...tap the table top and you will get concentric field lines whose spacing goes on increasing as you go away from the conductor.moving alpha particles surely produce such a field but not neutrons as they r not charged and not hence equivalent current
