Figure shows two long, straight wires carrying electric currents in opposite directions. The separation between the wires is 5.0 cm. Find the magnetic field at a point P midway between the wires.

Two long straight wires, each carrying a current I in opossite directions asre separated by a distasnce R . The magnetic induction at a point mid way between the wire is

Two long straight wires are set parallel to each other Each carries a current in the same directionand the separation between them is 2r. The intensity of the magnetic field midway between them is

Two long straight wires are set parallel to each other. Each carriers a current i in the same direction and the separation between them is 2r . The intensity of the magnetic field midway between them is

Two parallel wires carry equal currents of 10A along the same direction and are separated by a distance of 2.0 cm. Find the magnetic field at a point which is 2.0 cm away from each of these wires.

If current in two parallel wires flow in opposite directions, the force between the wires will:

Two long, straight parallel conductors each carrying 2A current in the same direction are 10 cm apart. Calculate the magnetic field at a distance a) at a point which is midway between the wires b) at a point which is 15 cm from one wire and 5cm from the other.

Figure shows two long parallel straight wires distance 5cm apart carrying currents 4A and 10A in opposite directions. Find the position of a point where the resultant magnetic field due to current in two wires in zero.

Figure. Shows two long wires carrying equal currents I_1 and I_2 flowing in opposite directions. Which of the arrows labeled A to D correctely represents the direction of the magnetic field due to the wires at a point located at an equal distance d from each wire?

Two infinitely long parallel wires carry equal current in same direction. The magnetic field at a mid point in between the two wires is
