MHT CET 2022 Physics question
Two parallel conducting wires of equal length are placed distance 'd' apart carry currents '' and '' respectively in opposite directions. The resultant magnetic field at the midpoint of the distance between both the wires is
Answer: (C)
Solution
The midpoint is at distance from each wire. Field due to a long straight wire: , so and . For currents in opposite directions, the fields of the two wires
