Answer:
Complete question:if a = 0.800 cm? (μ0 = 4π × 10-7 T · m/A)
Step-by-step explanation:
Given:
Distance between plates = 0.8 cm
Distance from one plate = 1 mm
Current density 'J'= 16 A/m
Currents are flowing in opposite direction.
When current is flowing in opposite direction then magnetic field given as
By putting the values we get
