Q19 of 32 Page 100

Meena draws magnetic field lines of field close to the axis of a current carrying circular loop. As she moves away from the center of the circular loop she observes that the lines keep on diverging. How will you explain her observation?

Since magnetic field is stronger near the current carrying conductor and weak when away from the conductor. In current carrying circular loop, the magnetic field lines are stronger at the periphery of the loop but as we move away i.e. towards the center of the loop, the magnetic field becomes weak there. As a result, the magnetic field lines looks like straight lines at the center and as we move near to the conductor i.e. towards periphery, the magnetic field lines seems like diverging so as to maintain the circular shape around the wire of the circular loop.

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.
