How does the Magnetic Field Wire Calculator work?

Enter current, distance from wire, and relative permeability Then: The calculator applies B = (μ × I) / (2π × r) Then: Results show magnetic field strength in tesla.

Can you give an example of how to use the Magnetic Field Wire Calculator?

Example: Input I = 10 A, r = 0.01 m (1 cm) gives a result of B ≈ 200 μT (Comparable to Earth's magnetic field).

Is the Magnetic Field Wire Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Magnetic Field Wire Calculator?

Our Magnetic Field Wire Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.

Did You Know?

The magnetic field around a single wire is weak, but coiling the wire (solenoid) concentrates field lines, creating much stronger electromagnets.
