Question

i) Name the rule that is used to find the direction of magnetic field associated with the current carrying conductor ii) is there a similar magnetic field produced around the thin beam of moving a)Alpha particles? justify your answer

Answer 1

i) Right Hand thumb rule
ii) any moving charge has a magnetic field associated with it, which is produced around it, and alpha particles are charged particles, so there is magnetic field produced around the alpha particles but the direction of the field is opposite to that of electrons because alpha particles are positively charged while electrons are negatively charged.
