In the figure, there is a conducting wire having current i and which has a shape of closed half ellipse [x2a2+y2 b2=1] is kept in a uniform magnetic field B as shown. The magnitude of magnetic dipole moment of loop and torque acting on it are-

The given figure shows a long straight wire of a circular cross-section (radius a)carrying steady current I. The current I is uniformly distributed across this cross-section. Calculate the magnetic field in the region r < a and r > a.

A long cylindrical wire (radius = 4 cm) carries a current of 22 A that is uniformly distributed over a cross-section of the wire. What is the magnitude of the magnetic field at a point that is 0.1 cm from the axis of the wire?

A cube of edge length ℓ = 2.80 cm is positioned as shown in the figure below. A uniform magnetic field given by = (4.7 î + 4.0 ĵ + 3.0 ) T exists throughout the region.
