Calculate the electromagnetic force using the equation:
\[ F = \frac{\mu_0\,N^2\,I^2\,A}{2\,l^2} \] where \( \mu_0 = 4\pi \times 10^{-7}\) H/m.

* Enter all values in SI units.

Step 1: Enter Parameters

Example: 100 turns

Example: 2 A

Example: 0.001 m²

Example: 0.05 m

Formula: \( F = \frac{\mu_0\,N^2\,I^2\,A}{2\,l^2} \)


Practical Example:
For a solenoid with 100 turns, a current of 2 A, a cross-sectional area of 0.001 m², and an effective length of 0.05 m:
\[ F \approx \frac{(4\pi \times 10^{-7}) \times 100^2 \times 2^2 \times 0.001}{2 \times (0.05)^2} \approx 1.01 \times 10^{-2}\, \text{N} \]
