Enter the emf intensity into the EMF Distance Calculator. The calculator will evaluate and display the EMF Distance. 

EMF Distance Formula

The following formula is used to calculate the EMF Distance. 

D = SQRT (1/I)
  • Where D is the EMF Distance (m)
  • I is the emf intensity 

To calculate the emf distance, take the square root of 1 over the emf intensity.

How to Calculate EMF Distance?

The following example problems outline how to calculate EMF Distance.

Example Problem #1:

  1. First, determine the emf intensity.
    • The emf intensity is given as: 2.5.
  2. Finally, calculate the EMF Distance using the equation above: 

D = SQRT (1/I)

The values given above are inserted into the equation below and the solution is calculated:

D = SQRT (1/2.5) = .632 (m)

Example Problem #2: 

For this problem, the variables needed are provided below:

emf intensity = .45

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

D = SQRT (1/I) = ?
