Questions
Two long parallel wires are kept at a separation . Magnitude of magnetic force experienced by unit length of each wire is F. If the separation between the wire is halved and current in each wire is doubled, then magnitude of force experienced by each wire will be
detailed solution
Correct option is C
F=μ0I22πr, F1=μ0I122πr1⇒F1F=I1I2.rr1=2II2.rr/2=8⇒F1=8 FTalk to our academic expert!
