A vertical straight wire carrying an upward 14.2 A current exerts an attractive force per unit length of 7.80E-4 N/m on a second parallel wire 7.60 cm away. What is the magnitude of the current that flows in the second wire?
For a current I1 = 14.2 Amperes and radial separation between wires r =0.076 m, the magnetic field at wire 2 is B =0.000037368 Tesla If current I2 = 21 Amperes then the force per meter is F/ΔL =0.000784 Newtons/m hyperphysics.phy-astr.gsu.edu/hba... Goodbye
