Solenoid Current Calculator

Formula

The formula to calculate the Solenoid Current (Is) is:

\[ Is = \frac{B}{u} \times \frac{L}{N} \]

Where:

\( Is \) is the solenoid current (amps).
\( B \) is the magnetic flux density (Tesla).
\( L \) is the length of the solenoid (m).
\( u \) is the magnetic constant.
\( N \) is the number of turns.

What is Solenoid Current?

Solenoid current refers to the electric current flowing through a solenoid, which is a coil of wire that generates a magnetic field when an electric current passes through it. The solenoid current is crucial in determining the strength of the magnetic field produced by the solenoid.

Example Calculation

Consider an example where:

Magnetic Flux Density (B): 0.5 T
Length of Solenoid (L): 2 m
Magnetic Constant (u): 4π × 10^-7 T·m/A
Number of Turns (N): 100

Using the formula to calculate the Solenoid Current:

\[ Is = \frac{0.5}{4\pi \times 10^{-7}} \times \frac{2}{100} \approx 796.18 \text{ A} \]

This means that the solenoid current for this example is approximately 796.18 amps.
