Two parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on it will be
Text Solution
Verified by ExpertsThe correct answer is:
B
F 1 = 
F 2 = 
F 1 and F 2 both points in the same direction towards 40 A wire.
