List of top Physics Questions on Magnetic Force on a Current-Carrying Wire

બે અનંત લાંબી સમાંતર વાહક તાર A અને B માં I અને 2I કરંટ સમાન દિશામાં છે. A ફ્લોર પર છે અને B, h ઊંચાઈએ છે. તાર A ઊઠતો ન થાય તે માટે h નું ન્યૂનતમ મૂલ્ય છે:
Two infinitely long parallel conducting wires \(A\) and \(B\) carry currents \(I\) and \(2I\), respectively, in the same direction. Wire \(A\) lies on an insulated floor while wire \(B\) is fixed at a height \(h\) above the floor. The minimum value of \(h\) so that wire \(A\) does not rise from the floor is:
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 1 cm segment of a wire lying along the x-axis carries a current of 0.5 A along the \( +x \)-direction. A magnetic field \( \vec{B} = (0.4 \, \text{mT} \hat{j}) + (0.6 \, \text{mT} \hat{k}) \) is switched on. The force acting on the segment is:
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 (\(\vec{v}\)):

A cylindrical conductor of radius R is carrying a constant current. The plot of the magnitude of the magnetic field, B with the distance, d, from the centre of the conductor, is correctly represented by the figure :
