About the Biot-Savart Law
The Biot-Savart law describes the magnetic field generated by a steady electric current. It is fundamental to understanding electromagnets, motors, and inductors.
Key Formulas:
- dB = (μ₀/4π)(Idl × r̂)/r²
- Straight wire: B = μ₀I/(2πr)
- Loop center: B = μ₀NI/(2R)
- Solenoid: B = μ₀NI/L
Constants:
- μ₀ = 4π × 10⁻⁷ T·m/A
- 1 Tesla = 10,000 Gauss
