An infinite surface of linear current density  exists on the  plane, as shown in the figure. The magnitude of the magnetic field intensity  at a point  due to the surface current in Ampere/meter is __________ (Round off to 2 decimal places).

A long conducting cylinder having a radius ‘b’ is placed along the z axis. The current density is  for the region r < b where r is the distance in the radial direction. The magnetic field intensity (H) for the region inside the conductor (i.e. for r < b) is

If the magnetic field intensity (H) in a conducting region is given by the expression, . The magnitude of the current density, in , at 𝑥 = 1 m, 𝑦 = 2 m, and 𝑧 = 1 m, is

A steady current I is flowing in the –x direction through each two infinitely long wires at  as shown in the figure. The permeability of the medium is. The -field at (0, L, 0) is
