In a previous video, Electricity and Magnetism, Karen talks about how they work together in electronics. In this video, Karen introduces a sensor that is triggered by magnetic fields, the hall effect sensor. While Karen has used reed switches, an electromechanical magnetic switch, in an escape room puzzle in a previous video, here she shows how hall effect sensors use magnetic fields as either digital (on/off) or analog (linear) switches that are purely electrical with no moving parts. This video continues the exploration of electricity and magnetism also covered in Intro to DC Motors and Intro to Speakers &amp; Microphones.</span></p><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: hall voltage, digital, electromagnetism, linear, e14presents_karencorbeill, magnetic flux, flux density, bipolar, polarity, schmidt trigger, e14_makerkaren, magnetic fields, electric current, lorentz force, permeability, magnets, air gap, analog, unipolar</div> https://community.element14.com/challenges-projects/element14-presents/thelearningcircuit/w/documents/5289/how-do-hall-effect-sensors-work----the-learning-circuit-89/revision/1Wed, 06 Oct 2021 22:35:41 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:222bb24d-29ba-447d-b7b9-649c9bd65bactariq.ahmadhttps://community.element14.com/challenges-projects/element14-presents/thelearningcircuit/w/documents/5289/how-do-hall-effect-sensors-work----the-learning-circuit-89#commentsRevision 1 posted to Documents by tariq.ahmad on 10/6/2021 10:35:41 PM<br /> <div style="background:#ffffff;padding:14px 16px 16px 18px;margin:0;vertical-align:top;border:1px solid #dadada;"><div style="float:left;display:inline-block;padding:0px 25px 8px 0px;"><a href="/challengesprojects/element14-presents/"><img alt="element14 presents" src="/e14/assets/legacy/2018/e14PresentsJune818.png" width="180px" /></a></div><div style="display:inline-block;vertical-align:top;width:70%;"><span style="font-size:18px;font-weight:bold;">How Do Hall Effect Sensors Work?</span><p style="margin:0;"><span><a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/thelearningcircuit/">The Learning Circuit</a></span> <strong>|</strong> <a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/">element14 presents</a> <strong>|</strong>&nbsp; <a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/project-videos/">Project Videos</a></p></div></div><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;"></p><span><a href="https://www.youtube.com/watch?v=dgyB2-1VDI0">www.youtube.com/watch</a></span><p style="margin:0;"></p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;border:1px solid #b8d7e5;background-color:#e9f6fc;padding:8px;max-width:744px;"><span style="color:#000000;font-family:&#39;Open Sans&#39;, Arial, sans-serif;text-align:justify;">At an atomic level, electromagnetic fields are what makes electricity work.
