WebIn fact, just a coil, in a direct current circuit, would be a short circuit and draw enormous current and blow a fuse or destroy something in the circuit. In such a circuit, increasing the number of turns in the coil would increase resistance by the same factor and the magnetic field would stay the same. But most circuits are not just a coil. Web29 nov. 2024 · Summary: This formula can be used to calculate the number of turns of a long solenoid, given the magnetic field, the length of the solenoid and the current. This …
