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
