## 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:

- First, determine the emf intensity.
- The emf intensity is given as: 2.5.

- 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.
