Two long parallel wires carry currents of 5A in opposite directions. They are separated by 40 cm. What is the magnitude of the magnetic field in the plane of the wires at a point P that is 20 cm from one wire and 60 cm from the other? (Ho=4n. 10-7T. m/A). Note: It doesnot matter how you choose which current goes into the page and which comes out. You only need to provide the magnitude of the field. 40 cm 20 cm P
