Nice ferrite core. http://www.stormwise.com/page28.htm Does anyone know why the coil below is housed in a 90 degree pipe? https://www.heartmath.org/gci/gcms/making-of-a-sensor-site/ Kevin Foster

As per P=I²R, doubling copper will halve the power consumption, but doubling the field strength quadruples the power consumption. Doubling both the cross-section and the length of the wire gets you a coil with 4 times as much copper, twice as many turns, four times the inductance, and the same DC resistance and as the original. -- This email has not been checked by half-arsed antivirus software
