The current in the second wire is 1.37 A.
Current in the second wire
The current in the second wire is calculated from the magnetic force between the two wires.
F/L = (μI₁I₂)/(2πr)
where;
- μ is permeability of free space
- I₂ is current in the second wire
- F/L is force per unit length
- r is the distance between the two wires
μI₁I₂ = (F/L 2πr)
I₂ = ((F/L 2πr) / (μI₁)
I₂ = (7.7 x ⁻⁵ x 2π x 0.082)/(4π x 10⁻⁷ x 23)
I₂ = 1.37 A
Thus, the current in the second wire is 1.37 A.
