Questions
Two long parallel current carrying conductors are carrying currents 2A and 4A in opposite directions. If the separation between the conductors is 1m, find the magnetic induction at a point midway between the wires.
detailed solution
Correct option is C
B=μ0i12πd2+μ0i22πd2=μ0πdi1+i2=4π×10−7π×12+4T⇒B=2.4 μTTalk to our academic expert!
