Solenoid Magnetic Field Calculator
Solenoid Magnetic Field Calculator computes the magnetic field strength inside a solenoid based on the number of turns, solenoid length, and current. Input the parameters, select units, and calculate the magnetic field.

How to Use Solenoid Magnetic Field Calculator:
- Enter the number of turns (N), solenoid length (L), and current (I) using the keypad or direct input; use “Next” to switch fields.
- Select appropriate units for length (m, cm, mm) and current (A, mA).
- Click “Calculate” to see step-by-step results.
- Use “Share Result” to get shareable text or “Copy Result” to copy to clipboard.
Formula:
Magnetic Field (B):
B = μ₀ × n × I
Where: B = magnetic field (T), μ₀ = permeability of free space (4π × 10⁻⁷ H/m), n = N / L (turns/m), I = current (A)
Important Notes:
- Inputs for number of turns and length must be positive; current can be zero or positive. Invalid inputs will trigger an error.
- The calculator assumes an ideal, long solenoid with a uniform magnetic field inside.
