Problem $2(5$ points$)$

a$)$ Identify a Hall effect sensor that provides a linear voltage output $($not switching$)$ in a range of at least $50$ mT $,$ and report the manufacturer, code, and a link for purchasing it online

b$)$ Sketch the schematic of a system where a Hall effect sensor is used to measure a mechanical quantity $($i$.$e$.,$ position, contact, distance, force$).$ For the selected system, please specify whether you would use a linear, or a switching Hall$-$effect sensor
