Question

Two long wires each carry a current of one amphere. The current is in the same direction in both wires. The distance between the wires is 2cm. What is the value of the magnetic field at a point P which is at the same distance of one centimeter from both wires? (The point P is between the wire). Two long wires each carry a current of one amphere. The current is in the same direction in both wires. The distance between the wires is 2cm. What is the value of the magnetic field at a point P which is at the same distance of one centimeter from both wires? (The point P is between the wire).

Explanation / Answer

The point is between teh wires and is equi distant

so the magnitude of magnetic field willbe equal

since the current is flowing in the same direction

the direction of magnetic field by botth the wires will be in opposite directions

so net Magnetic field at point P will be zero
