Enter the number of gausses, distance of the magnetic field, and the current into the calculator to determine the pull force.

Gauss to Pull Force Formula

The following equation is used to calculate the Gauss to Pull Force.

F = G * 0001 * I * D 
  • Where F is the pull force (N)
  • G is the magnetic flux density (10^-4 kg/A*s^2)
  • I is the current (amps)
  • D is the distance of the magnetic field (m)

To calculate the pull force, multiply the magnetic flux density by .0001, then multiply by the current, then finally multiply the distance of the magnetic field.

What is a Gauss?


A gauss is a unit of measurement used to express the density of a magnetic field. The gauss was named for Carl Friedrich Gauss, who first described the phenomenon and formulated mathematical descriptions of electromagnetism.

The gauss is defined as one maxwell per square centimeter. One maxwell represents a magnetic field in which a line of force (a flux) has an area of one square centimeter perpendicular to it. The maxwell is not generally used as a unit of measure. Still, it can be thought of as the flux generated by one coulomb of charge moving with a velocity of one centimeter per second and a wire one centimeter in length in a direction at right angles to that wire.

How to Calculate Pull Force from Gauss?

Example Problem:

The following example outlines the steps and information needed to calculated pull force from gauss.

First, determine the flux density. In this example, the flux density is 400 gauss.

Next, determine the current. The current is measured to be 120 amps

Next, determine the distance from the magnetic field. In this example, the distance is 5 meters.

Finally, calculate the pull force using the formula above:

F = G * 0001 * I * D

F = 400 * 0001 * 120 * 5

F = 24 N
