And to prepare such a question, you will need enough information to begin the design e.g. google.com/search?q=solenoid+plunger+design+book | |

| Aug 15, 2022 at 6:16 | comment | added | Tito | @aconcernedcitizen i am make solenoid lock (high pulling force) using 220v AC, so i need good resistance of the coil, the impedance of this now is 3.6 which means it output 61A!!!. I need it works on 3-5A | |

| Aug 15, 2022 at 0:37 | comment | added | user136077 | You use the wire ineffectively if you aim to certain inductance (=150 mH) Try bigger coil diameter, say 10 cm and as tightly packed turns as possible. As few as 310 turns (about 100 meters of total wire length) can be enough - should be measured and fixed when done, because it's based on approximate formulas. An iron or ferrite core would reduce the needed turns radically, but a solid iron bar wouldn't work, it should be an eddy current free construction if you want to use it with AC or non-constant DC. | |

| Aug 15, 2022 at 0:05 | comment | added | Mattman944 | The formulas are going to assume that each turn is tightly packed with the adjacent turns. If you want maximum inductance, you can't just randomly wind onto a spool. coil32.net/multi-layer-coil.html 66pacific.com/calculators/coil-inductance-calculator.aspx | |
| Aug 14, 2022 at 23:59 | comment | added | user57037 | To a first approximation, add more turns. Inductance is proportional to the square of the number of turns. So you need a total of 6000 * sqrt(150/3.7) = 38,000 total turns. There are also formulas for air-core inductors. electricaltechnology.org/2014/03/… | |
