Working Principle

The magnetic field inside a straight solenoid is directly proportional to the current flowing through it and the number of turns per unit length. The formula used is:

B = μ₀ * n * I

Where:

  • B is the magnetic field strength in Tesla (T).
  • μ₀ is the permeability of free space, approximately 4π × 10⁻⁷ T·m/A.
  • n is the number of turns per unit length in turns per meter (turns/m).
  • I is the current in Amperes (A).

This calculator helps you determine the strength of the magnetic field inside a solenoid, which is useful in various physics and engineering applications.
