How to Use the Calculator

  1. Enter the number of turns (N) in the magnetic coil.
  2. Enter the current (I) flowing through the coil in Amperes.
  3. Enter the magnetic length (L) of the magnetic circuit in meters.
  4. Click the "Calculate" button to compute the Magnetic Motive Force (MMF).
  5. The result will be displayed in Ampere-Turns.

Working Principle

The Magnetic Motive Force (MMF) is the force that drives magnetic flux through a magnetic circuit. It is calculated as the product of the number of turns in a coil and the current flowing through it. The formula is:

MMF = N × I

Where:

  • MMF = Magnetic Motive Force in Ampere-Turns
  • N = Number of turns in the coil
  • I = Current in Amperes

Applications

This calculator is useful in various applications including:

  • Designing electromagnets
  • Calculating the performance of magnetic circuits in devices like transformers and motors
  • Understanding the magnetic properties of different materials
