Physics Information
Magnetic field strength (B): 3.5 × 10⁻⁵ T
The field is calculated using: B = (μ₀I)/(2πr)
Where:
- μ₀ = 4π × 10⁻⁷ Tm/A (permeability of free space)
- I = Current in wire (A)
- r = Distance from wire (m)
Field direction (Right-Hand Rule)
Key observation: The magnetic field forms concentric circles around the wire, with strength decreasing as 1/r. The direction follows the right-hand rule (thumb in current direction, fingers curl in field direction).
