WebOur online calculator allows you to calculate the coreless inductor using the Maxwell elliptic integral method: Required Inductance L Frame diameter D Winding length l Copper wire Why did OpenSSH create its own key format, and not use PKCS#8? The last equation computes the time constant of an RL circuit, a circuit composed of a single resistor and indctor. Always bear in mind that there is a tolerance on the stated AL value of a core. taking 1 and dividing it by this time value, you get the frequency. So, if we picked a core with a gap of 0.25 mm (250 m), the AL value has reduced to 1000, and this means that we need more turns to produce 1 mH inductance. $$N = \sqrt{\dfrac{0.15\text{ H} \times 0.79\text{ m}}{4\pi\times 10^{-7} \frac{H}{m} \times 0.06605\text{ m}^2}} = 1195 \text{ turns}$$.
