Teaching UP B.Ed (Paper 1 & 2) Mock Test 2025 Physics Moving Charges and Magnetism Force Between Two Parallel Currents
Two current carrying long wires are placed parallel to each other and separated by a distance d. If the force on the segment of the wires is F, then the force F is related to d as:
1
F ∝ d2
2
F ∝ d
3
\(F\propto\frac{1}{d}\)
4
\(F\propto\frac{1}{d^2}\)
