Utilize our EMF Calculator to quickly determine the magnetic flux density (B) generated by a current-carrying wire. Understand electromagnetic field strength in your environment and assess potential exposure levels. This tool is vital for health and safety planning around electrical sources.
Formula:
The magnetic flux density (B) at a distance 'r' from a long straight wire carrying current 'I' is given by:
B = (μ₀ * I) / (2πr)
Where:- B = Magnetic Flux Density (Tesla)
- μ₀ = Permeability of free space (4π × 10-7 N/A2)
- I = Current (Amperes)
- r = Distance from the wire (meters)
