Two identical coaxial circular loops carry a current i each circulating in the same direction. If the loops approach each other

Magnetic flux is Φ=∫B⃗·dA⃗ and induced emf is ε=−dΦ/dt. Apply Lenz’s law for direction and I=ε/R when the circuit is resistive. This gives the current in each will decrease.
