The Biot Savart Law Calculator serves as a valuable tool in physics and engineering, enabling the precise computation of the magnetic field at a designated point in space created by a current-carrying wire. This calculator operates on the principles of the Biot-Savart Law, a fundamental concept in electromagnetism elucidating the magnetic field’s generation due to a steady electric current. By inputting essential parameters like the current through the wire, the differential length element along the wire, and the position vector from the differential element to the desired point, users can efficiently ascertain the magnetic field strength.
Formula of Biot Savart Law Calculator
The Biot-Savart Law is mathematically expressed as:
B = (μ₀ / (4π)) * ∫ (I * dl × r) / r³
Variables:
- B represents the magnetic field at a point.
- μ₀ (mu naught) is the permeability of free space, approximately equal to 4π x 10⁻⁷ T·m/A (Tesla meters per ampere).
- I is the current flowing in the wire. dl represents a differential length element along the current-carrying wire.
- r is the position vector pointing from the differential element to the point where you want to calculate the magnetic field.
- × denotes the cross product.
- The integral symbol (∫) indicates that you need to integrate this expression along the entire length of the wire to find the total magnetic field at a specific point.
