Educational video on how automotive induction and hall effect rotational speed sensors work and the types of electrical signals they produce. I found this video on Magneto Resistive speed sensor video very helpful • Magnetic Sensors Basic...

    Excellent work here. The animations really show the processes well, and the reading of the material is well done too. Thank you for this, my air gap is now adjusted properly, Jim.

    when we explain current as alternating does it mean when the current goes from the hot wire through the load and back to the panel on the neutral or does it alternate in the cable as it moves around the circuit?

    This hall effect switch is not alternating current. This is direct current. Alternating or AC current travels from zero to a positive voltage, then back to zero, then to a negative voltage, then back to zero while it's on it's way pack to positive. When viewed on an oscilloscope this would be called a sine wave. Think of a regular size D flashlight battery positive terminal connected to a light bulb with a red wire. a black wire from the other side of the light bulb has the black wire t connected to the negative side of the battery. The light bulb will now light up. Now quickly flip the battery so the black wire is on positive and the red wire is on negative. You just alternated the current in the other direction. Now flip the battery back again, Red to pos. and black to neg. Flip it again, and again and again. This light is now being light by Alternating current. Only in a house this happens 60 times a second. To fast for our eyes and brains to process that the light has flickered off and on again. I hope this helps.

    Can you make also sir a video how it happens this magnetic encoder ring tooth less design iterrupt electromagnetic field inside the wss? Unlike magnetic tooth ring easily to understand.

    Sir I really appreciate of this video but my understanding is limited and I do believe "Understanding is better, than memorizing"...now I just want to understand what I experience hoping your help, cause I believed your understanding of this is deeper than mine. I just want to ask sir, I encounter an active WSS two wire one wire 12V supply inside the module procedure called it "control" other wire is pulled down resistor inside the module where the module monitored or has voltage sensing before the resistor going to low reference procedure called it"signal" that produces frequency modulated to module, now as I back probe this "control" wire with circuit intact, ign. ON vehicle stationary, I read close to 12V, on signal wire is OV. Now I tried to disconnect the connector at the WSS then check again same process ign ON, on control wire I read OV, on signal wire I read 4.5V, this system use magnetic encoder ring that has no tooth not same on this video, this design use together on hub bearing assy.that I'ved seen on last portion of this video. Signal wire use a pulled down resistor, and not same on this video on a positive side the module monitored, now I wondering sir, I'm talking about this vehicle I'ved check as I watched this video if vehicle is stationary and ign.switch ON, voltage inside the module is present up to transistor feed side only on the 12V control circuit, thats why I read close to 12V on control side, circuit intact and read OV on the signal circuit with ign.ON. Opposite to your video as it ON electromagnetic field build up causing transistor to energized switch close. Now on this design I'ved mentioned sir what causes the transistor inside wss to energized? Is the encoder ring produces magnetic field? How? I mean if it is,how? While vehicle stationary magnetic field is there on encoder ring itself, why not closing the transistor if the magnetic field cause it to energized? Or if ign.ON their's electromagnetic field build up inside wss why I read OV on signal if electromagnetic field can energized transistor and not close to 12V? By the way sir this Car I have check is no issue I just check this after I watched your video as my curiosity.😁 And to proved myself if its happening like on this video but I'm confuse for what I have measured using DMM and this 2022 GMC yukon. I want to stress my mind to dig deeper of understanding what engineers design and as my curiosity always eager to gain more and more knowledge about automotive fields from you and from our service info. But in service info.not explained in detailed on circuit testing and whats happening inside the module so that I or we field techs. Accurately perform our diagnostic ability thanks sir for your informative video,hope you will reply....god bless always...😊

    You have a Magneto-Resistive speed sensor and here are some resources to understand how they work and how to test them. You really need an oscilloscope for accurate testing. Check out these resources.

    I don't think that your explanation at the end was accurate, it was actually misleading. You didn't mention the resistor in series before the measurement module. The principle behind the change in voltage is actually voltage drop. You made no mention of the resistor, if there wasn't a resistor then there would simply be no voltage drop.

    Right at time stamp 5:12 it states "the measured voltage value drops to zero". It's just another way of saying there is a voltage drop. I don't talk about the resister because that is not the true focus of the video and how the sensors work. The resistor is critical because without the resistor the circuit would short out every time the circuit is switched to ground by the transistor. The resistor is a current limiter to prevent computer burnout. The video also assumes the viewer understand a simple circuit. Power source, load, switch and conductors. I'm sorry this video fell short for you or it didn't have what you were expecting. One of my goals is to keep my videos as short as possible. If I had to explain the function of how a circuit works that would add minutes onto a speed sensor video while at the same time turning the video into a basic electrical video.
