Two parallel conductors are carrying currents in the samedirection.The currents are nonzeroand not necessarily equal. The magnitude of the magneticfieldmidway between themis 40 μT. If one of the currents then has its directionreversed,what is the resultingmagnitude of the magnetic field midway between them?a. a value greater than 40 μTb. 40 μTc. a value less than 40 μTd. It could be any value.
Two long straight wires are parallel and carry current in opposite directions. The currents are 10 amps and 15 amps and the wires are separated by 0.40cm. What is the magnetic field due these currents at a point midway between the wires?
