Hold the probe and drag it to the tip of a leg. Tapping works too: first pick the probe, then the leg.

Set the range to Ω (resistance).

Measure step by step

A multimeter cannot measure inductance; it only sees the DC resistance of the coil wire. A good coil shows a low resistance and beeps on continuity. It has no direction.
