This air-core inductor is made from 20 gauge copper wire. It has an inductance of 5 mH and low resistance. A metal core can be added to increase inductance.
This inductor is used in many physics experiments, including some in our Advanced Physics with Vernier – Beyond Mechanics book. It is an air-core inductor is made from 20 gauge copper wire. It has an inductance of 5 mH and a resistance of 2.4 ohms. It is rated at 200 Watts. A metal core (not included) can be added to increase inductance.
For RL or RLC circuit experiments, we recommend using this inductor in combination with our Vernier Circuit Board. The ends of the coil wire are exposed so that you can easily make connections to the Vernier Circuit Board or to other components or sensors.
