362742 A metal wire of mass \(m\) slides without friction on two horizontal rails placed at a distance \(l\) apart. The track lies in a uniform vertical magnetic field \(B\). A constant current i flows along the rails across the wire to the other rail. The acceleration of the wire is

362743 A rigid wire consists of a semicircular portion of radius \(R\) and two straight sections. The wire is partially immersed in a perpendicular magnetic field \(\vec{B}=B_{0} \hat{j}\) as shown in figure. The magnetic force on the wire if it has a current \(i\) is

362744 A square current carrying loop is suspended in a uniform magnetic field acting in the plane of the loop. If the force on one arm of the loop is \(F\), the net force on the remaining three arms of the loop is:
