The opposition offered by a coil to the flow of alternating current (disregard resistance) is called?

Explanation:
When a coil is in an alternating current circuit, its opposition to the changing current comes from the magnetic field it builds up and collapses. This specific opposition is called inductive reactance. It depends on frequency and the coil’s inductance (X_L = 2πfL), and for an ideal coil with no resistance, the impedance is purely reactive and equals this inductive reactance (Z = jX_L). Reluctance is a magnetic-path property, not the electrical opposition in the circuit. Reactance is the general reactive part, but for a coil the proper, specific term is inductive reactance.
