Primary/Secondary Coils – COMING SOON
COMING JUNE 2026
These nested primary and secondary coils have a removable soft iron core.
Each coil has safety banana jacks. The inner coil has 302 turns of wire, and the outer coil has 3077 turns of wire, making the ratio of turns approximately 10:1.
The direction of the winds is marked with an arrow.
Applications
- Step-up and step-down transformers
- Magnetic field inside a solenoid (using the outer coil)
