Distance From Wire (m)

Insert the information in the form and the calculator will determine the magnetic field.

What is the magnetic field?

The magnetic field strength is the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself.

How to calculate magnetic field?

To calculate magnetic field you should use the following formula:
magnetic field strength around wire = (k * current) / distance from wire
where:
k = 2e-7

Why use magnetic field?

The magnetic field is used in ordr to measure the strength or the weakness of the magnetic field.
