Two long, straight wires carry equal currents in opposite directions as shown in figure. The separation between the wires is 5.0 cm. The magnitude of the magnetic field at a point P midway between the wires is μT. (Given: μ₀=4π×10⁻⁷ T m A⁻¹)

Question

Accepted Answer

160. P is 2.5 cm from each wire; opposite currents give fields in the same direction between the wires. B=2×(2×10⁻⁷×10)/(0.025)=1.6×10⁻⁴ T=160 μT → 160
