A researcher would like to perform an experiment in a zero magnetic field, which means that the field of the earth must be cancelled. Suppose the experiment is done inside a solenoid of diameter 1.3m , length 5.0m , with a total of 9000 turns of wire. The solenoid is oriented to produce a field that opposes and exactly cancels the field of the earth.
Part A What current is needed in the solenoid's wires?
a charged particle is injected at 211 m/s into a 0.0627- T uniform magnetic magnetic field perpendicularly to the field, What is the charge to mass ratio of this particle
