1.A semicircular wire of radius 5.0 cm carries a current of 5.0 A.A magnetic field B of magnitude 0.50 T exists along the perpendicular to the plane of the wire.Find the magnitude of the magnetic force acting on the wire.
2.A wire carrying a current i is kept in the X-Y plane along the curve y =A sin[2
x/lambda].A magnetic field B exists in the z-direction .Find the magnitude of the magnetic force on the portion of the wire between x=0 and x=lambda.
