A solenoid is a tightly wound helical coil of wire whose diameter is small compared to its length. The magnetic field generated in the center, or core, of a current-carrying solenoid is essentially uniform and is directed along the axis of the solenoid. A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. Solenoids can convert electric current to mechanical action, making them very commonly used as switches. The magnetic field within a solenoid depends on the current and the density of turns. Magnetic field inside a long solenoid equation: B = µ₀ * N * I / L Where: B - Magnetic field N - Number of turns in the solenoid I - Electric current L - Length of the solenoid µ₀ - 1.25664 * 10^-6 T*m/A is the vacuum permeability Thank you for your support.
