A type of transmission line for electromagnetic waves consists of two parallel conducting plates (assumed infinite in width) separated by a distance aaa. Each plate carries the same uniform surface current density of 16.0 A/m, but the currents run in opposite directions. What is the magnitude of the magnetic field between the plates at a point 1.00 mm from one of the plates if aaa

Complete question:if a = 0.800 cm? (μ0 = 4π × 10-7 T · m/A)

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

the answer would be c
