Answer:
Twice the initial value
Explanation:
Let the current be = I
the width of the conducting strips be = a
We know that magnetic field between two plates is given by
If the direction of this magnetic field is same between the two plates, then
= 0
And when the currents runs opposite at each plate, then
Hence the magnetic field will be twice the initial value of the magnetic field that runs between the plates.
