A current is flowing through a conducting hollow pipe whose area of cross-section is shown in the fig. The value of magnetic induction will be zero at-

Current flows through a metallic conductor whose area of cross-section increases in the direction of the current. If we move in this direction.

Assertion : If a current is flowing through a conducting wire of non-uniform cross-section, drift speed and resistance both will increase at a section where cross-sectional area is less. Reason : Current density at such sections is more where cross-sectional area is less.
