Determination of the Self-Inductance of a Metal Ring.
Peer reviewed Peer reviewed
Mak, S. Y.; Young, K. – Physics Education, 1986
Describes a simple method for determining self-inductance of non-ferromagnetic rings. Suggests fitting the ring with an auxiliary coil and using a solenoid driven with a known frequency alternating current. Amplitude change and phase shift can be measured and used to calculate inductance. Material list, calculations, and sample results are given.…
