(A): The current density remains constant in a conductor of non uniform cross-section, carrying steady current. (R): The drift speed of electrons is cosntant in a conductor of non-uniform cross-sec tion which is carrying current.

A straight thick long wire of uniform cross-section of radius 5cm is carrying a steady current 5A . Calculate the magnetic field at a point 2cm from the axis of wire, well inside the wire.

A wire has non-uniform cross-section as shown in fig. steady current flows through it. The drift speed of electrons at point P and Q is v_(P) and v_(Q)

The magnetic field due to a straight conductor of uniform cross - section of radius a and carrying a steady current is represented by

Figure shows a long straight wire of a circular cross-section (radius a) carrying steady current l. The current l is uniformly distributed across this cross-section. Calculate the magnetic field in the region r lt a and r gt a
