A Hall Effect apparatus is used in labs to study charge carriers in materials by applying a magnetic field to a current-carrying semiconductor, generating a measurable Hall voltage, allowing determination of carrier type (electrons/holes), density, mobility, and resistivity, while in real-world applications, these principles power magnetic sensors for RPM sensing, position detection (ABS), current measurement, and non-contact switches in electronics, automotive, and industrial automation.
