AI Overview
There isn't a single "eddy flux density" formula; instead, eddy currents (which cause flux changes) are found using Maxwell's equations (often numerically), but the resulting magnetic flux density (B) is calculated as B = Φ/A (Flux/Area) or B = μH (permeability times field strength), with eddy current losses themselves often estimated by Steinmetz's equation for power loss (Pₑ ∝ ƒ² B²ₘₐₓ), showing eddy currents are part of the complex system, not a simple direct calculation from one formula.
Fundamental Flux Density Formulas:
General Definition: B = Φ/α
B: Magnetic Flux Density (Tesla, T)
Φ: Magnetic Flux (Weber, Wb)
A: Cross-sectional Area (m²)
Material Relationship: B = μH
B: Magnetic Flux Density (T)
μ: Magnetic Permeability of the material (H/m)
H: Magnetic Field Strength (Amperes/meter, A/m)
Eddy Currents & Losses:
Eddy Currents (J): These are induced currents within conductive materials when exposed to changing magnetic fields, described by Ohm's Law for conductors: J = σE (Current Density = Conductivity * Electric Field).
Power Loss (Steinmetz): To find the energy lost to eddy currents (and hysteresis), you often use empirical equations like Steinmetz's, where power loss (P) is related to frequency (ƒ) and peak flux density (Bₘₐₓ): P ∝ ƒ B²ₘₐₓ (simplified).
How They Relate:
1. A changing magnetic field (H) induces electric fields (E).
2. These electric fields drive eddy currents (J) in the material.
3. These eddy currents create their own magnetic fields, which oppose the original change (Lenz's Law).
4. This whole interaction is complex, often requiring finite element analysis software for precise B-field calculations, but the fundamental relationship B = μH always holds, with μ changing due to the eddy currents.
