Enter the current (amps) and the radius (m) into the Calculator. The calculator will evaluate the Magnetic Strength.

## Magnetic Strength Formula

MS = I /2*pi*r

Variables:

• MS is the Magnetic Strength (amps/meter)
• I is the current (amps)
• r is the radius (m)

To calculate Magnetic Strength, divide the current by 2, multiply by pi, then multiply again by the radius.

## How to Calculate Magnetic Strength?

The following steps outline how to calculate the Magnetic Strength.

• First, determine the current (amps).
• Next, determine the radius (m).
• Next, gather the formula from above = MS = I /2*p*r.
• Finally, calculate the Magnetic Strength.
• After inserting the variables and calculating the result, check your answer with the calculator above.
