Use the EMF calculator to see the approximate level of magnetic fields (measured in milligauss) that you would typically find at a certain distance from different types of electrical infrastructure. To use the calculator:

  1. See the images above to help you identify the type of infrastructure.
  2. Select the infrastructure type from the drop-down menu.
  3. Select a distance from the drop-down menu to see the approximate magnetic field level.

Typical average magnetic field level 0.00 mG

This calculator is for illustrative purposes. Levels of magnetic fields can vary.
