Current Sensor Simulator
Estimate the magnetic field and output voltage for Hall IC current sensing placement
C-Core Magnetic Circuit Simulator
Simulate the magnetic circuit of a C-core transformer and estimate the Hall sensor output voltage.
The magnitude of the magnetic field (B) within the air-gap of a C-core can be calculated using the simplified magnetic circuit equation:
B = Iμ₀lr
Where:
- B : magnetic flux density [T]
- I : primary current [A]
- μ₀ : permeability : 4π × 10⁻⁷ [H/m]
- lr : Air-gap length [mm]
