Use Xₗ=ωL, X꜀=1/(ωC), Z=√[R²+(Xₗ-X꜀)²] and Iᵣₘₛ=Vᵣₘₛ/Z. The circuit condition gives B: If the current in the loop ABCD is in clockwise sense then the induced current in the loop EFGH due to this current is in clockwise sense. µ₀ 2k; C: emf induced in the loop EFGH due to current in the loop ABCD is 4πd 3µ₀ 2k.
