Maxwell-Faraday's Law and the generation of eddy currents. A flexible shaft from the vehicle transmission rotates a disc magnet. The rotating magnetic field induces eddy currents in a spring-loaded cup, creating torque that moves the needle. Key variables for eddy current pe*******on depth (δ) include frequency (f), magnetic permeability (μ), and conductivity (σ) 🌈💡🔋
