A wire AB is carrying a steady current of `12A` and is lying on the table. Another wire CD carrying current `5A` is held vertically above AB at a height of 1mm. Find the mass per unit length of the wire CD so that it remains suspended at the position when left free. Give the direction of the current flowing in CD with respect to that in AB. `g=10ms^-2`.

A wire AB is carrying a steady current of 12A and is lying on the table. Another wire CD carrying 5A is held directly above AB at a height of 1mm. Find the mass per unit length of the wire CD so that it remains suspended at its position when left free. Give the direction of the current flowing in CD with respect to that in AB. [Take the value of g = 10ms^-2 ]

The resistance per unit length of the wires in segments AB, BC, CD, and AD are the same. The magnetic field due to the current at point O is

A current I_(1) carrying wire AB is placed near another long wire CD carrying current I_(2) . If wire AB is free to move, it will have
