Magnetic Strength Calculator

Formula

To calculate the Magnetic Strength:

$MS = \frac{I}{2 \pi r}$

Where:

$MS$ is the Magnetic Strength (A/m)
$I$ is the current (amps)
$r$ is the radius (meters)

Magnetic Strength Definition

Magnetic strength, also known as magnetic field strength, refers to the intensity of a magnetic field produced by a current-carrying conductor. It is calculated by dividing the current by 2, multiplying by pi, and then multiplying again by the radius.

Example Calculation 1

Let's assume the following values:

Current ( $I$ ) = 10 amps
Radius ( $r$ ) = 0.5 meters

Using the formula:

$MS = \frac{10}{2 \pi \times 0.5} = \frac{10}{\pi} \approx 3.183$

The magnetic strength is approximately 3.183 A/m.

Example Calculation 2

Let's assume the following values:

Current ( $I$ ) = 20 amps
Radius ( $r$ ) = 1 meter

Using the formula:

$MS = \frac{20}{2 \pi \times 1} = \frac{20}{2 \pi} \approx 3.183$

The magnetic strength is approximately 3.183 A/m.
