List of top Physics Questions on Magnetic Force on a Current-Carrying Wire asked in CUET (UG)

A horizontal wire of length \(10\,\text{cm}\) and mass \(0.3\,\text{g}\) carries a current of \(5\,\text{A}\). The magnitude of the magnetic field which can keep the wire in suspension is \[ (g=10\,\text{m s}^{-2}) \]

A conductor is placed along z-axis carrying current in z direction in uniform magnetic field directed along y-axis. The magnetic force acting on the conductor is directed along:

A square loop of copper wire is pulled through a region of uniform magnetic field as shown. Rank the pulling forces \(F_A\), \(F_B\), \(F_C\), and \(F_D\) that must be applied to keep the loop moving with constant speed (\(\vec{v}\)):
