With the help of a labelled circuit diagram, illustrate the pattern of field lines of the magnetic field around a current-carrying straight long conducting wire. How is the right hand thumb rule useful to find direction of magnetic field associated with a current-carrying conductor?

Which law helps to find direction of magnetic field around a current carrying conductor?

Write the help of a labelled circuit diagram describe an activity to illustrate the pattern of the magnetic field lines around a straight current carrying long conducting wire. (i) Name the rule that is used to find the direction of magnetic field associated with a current carrying conductor. (ii) Is there a similar magnetic field produced around a thin beam of moving: (a) alpha particles and (b) neutrons? Justify your answer.
