Problem
A straight copper wire of length 20 cm carries a steady current of 8 A. Only 6 cm of the wire lies inside a region of uniform magnetic field while the remaining portion is outside the field.
(i) Will the sections of the wire outside the field experience any magnetic force? Give reason.
(ii) State the length that must be used while calculating the magnitude of the magnetic force on the wire.
