Magnetic Flux Integration Calculator Usage Guide

Learn how to use the Magnetic Flux Integration Calculator and understand the principles behind magnetic flux calculation.

How to Use the Calculator

  1. Enter the magnetic field strength (B) in Tesla. This is the magnitude of the magnetic field.
  2. Input the area (A) over which you want to calculate the magnetic flux in square meters.
  3. Specify the angle (θ) between the magnetic field vector and the normal to the area. The angle should be between 0° (field is perpendicular to area) and 90° (field is parallel to area).
  4. Click the "Calculate" button to compute the magnetic flux.
  5. The result will be displayed in Weber, the SI unit for magnetic flux.

Understanding Magnetic Flux

Magnetic flux (Φ) is a measure of the total magnetic field passing through a given area. It's calculated as the dot product of the magnetic field vector and the area vector. The formula Φ = B × A × cos(θ) comes from this vector relationship.

When the magnetic field is perpendicular to the area (θ = 0°), the cosine of the angle is 1, and the flux is simply the product of the field strength and area. When the field is parallel to the area (θ = 90°), the cosine is 0, resulting in zero magnetic flux through that area.
