Designing a square loop coil
This calculator will help you to perform the calculation of a circular loop coil. The formula used in the calculator is sufficiently accurate for inductances not exceeding
hundreds of microhenres. If you need greater inductance you should use more adequate methods. You can:
- enter the number of turns n, the loop side a and the wire diameter d, and the calculator will compute an estimated value of inductance L
- enter the number of turns n, the wire diameter d and the inductance L, and the calculator will compute an estimated value of loop side a
- enter the loop radius R, the wire diameter d and the inductance L, and the calculator will compute an estimated number of turns n
Additionally the calculator will compute the total wire length and the estimated resistance of the winding. If you enter the value of frequency f, the calculator will estimate the expected Q-factor for the coil. Don't forget to select proper units for all the fields!
