1.	In which condition is the magneticforce actingona given current - carryingrod placed in a magneticfield maximum andin which condition wouldthe magneticforce not act on the rod ? (Assume that the current through the rod and the strength of the magnetic fieldare notchanged).
Answer» Solution :(1) Whenthe DIRECTIONOF theelectric currentpassing through the rod is PERPENDICULAR to the directionof the magnetic field, maximumforceis exertedon the rod. (2)Whenthedirection of the electric currnetis the sameas THATOF the magneticfieldor isoppositeto thatof the magnetic field, noforceis EXERTED on the rod.
