The 4 Right Hand Rules of Electromagnetism ("Easiest explanation on entire YouTube!") 

Bout to go take a College Level Physics test…. And you’re the first person who’s actually listed them all next to each other and explained the differences. Thank you thank you thank you 🙏🏼

Fantastic Iain! I am taking signals & systems next semester and you are going to be my secret weapon!

I love the helpful hand pictures. Most professors draw something horrible and are apologetic about it hahah

This was incredibly helpful. Your explanations make it very easy to follow, and everything I've had scrambled in my head during class is sorted out thanks to you! Thank you so much!!

thank you very much for the direct explanation as well as the illustration!

Simply Brillaint Professor /Dr Collings . It helps us revise and revisit and in many cases understand the concepts ( we studied in school ) more lucidly. I enjoy all your video series on digi comm. Keep up the great work and thank you very much .

Simply brilliant. Thank you.

simple and straight to the point! thank u

Clears up my confusion. Thank you!

Well that was really helpful..!! Earned my Subscription..!! This particular topic is one that should be simple, but can prove to be quiet confusing.. Excellent job explaining..!!

Thank you so much. Learned and understood more within the first 2 minutes of the video about this subject than I did 30 minutes of lecture from my physics with Calculus class

This helped so much. Thank you !

Hi there, I'm from South Africa. Thank you very much for this short and wonderful explanation. It's exactly what I needed.

thankyou so much!! it cleared a handful of my doubts 🙏.

Needed this!!

Thanks!

Very helpful. Thank you!

Super helpful! Thank you!!

I am on my third year of Engineering and it is quite a shame to say that today I got out of my confusion. Thank you very much!!! (Btw, I passed my course of Signals and Systems because of you, I am extremely grateful!!!)

Thanks ❤ Love from India🇮🇳

Brilliant way to explain. I am about to take my physics exam in an hour and this just clarified a concept that I had no idea how to do. Cheers lain.

You are a life saver! thank you!

thanks!

Thanks sir. I’m reviewing for my physics 2 final exam😊 Just wanna mention, for the second right hand rule in the video, I usually use the thumb to represent the direction of force, the fingers point to the direction of the current, while the fingers bend according to the direction of magnetic field. In such a case, the hand will adjust to the direction that suits the 2 direction, eventually having the correct direction for the force.

yes i agree with both of u👍👍

First! Also I very much appreciate these different explanations being told together, in context, so there’s less confusion!

I found the right hand rules very useful initially, but to be honest these days when working out the cross product vector directions, I just imagine a right handed coordinate system. I think of the first vector pointing in X, the second vector pointing in Y then I naturally find it easy to imagine the Z axis where the Vector Product Lays.

Thank you very much

I honestly don't understand why this is so necessary for highSchool Students.. 😔 😔

Oh thank you very much. You helped me understand a lot. from Egypt 🇪🇬🇪🇬❤❤❤❤❤❤

Thank you so much! I have an exam tomorrow and u are like a life saver for me right now.

Thank you sir!

thank you!

thank you!!!!

Thank you😁🌹

Thank you

Thank you so muchhhhhhhhhh❤️❤️❤️❤️

thx

Thanks for this I think am getting the hang of thanks to you.

Thankyou sir This video help me aloy in my competitive exams again thanks

This video deserves million of views and likesssss❤

legend

thanks really

Fantastic explanation. I am learning how to do some basic wiring and this is really helping me understand the fundamentals. One question: these rules are for conventional current, not electron flow, correct?

Excellentvidei, thank you, but just two small questions if I may, regarding the first two rules, you say B is into the page, but isn't it both going I abd coming out of the page? And also what about the index finger, I learned Flemings right hand rule but used the index finger. Thanks again

OMG! I absolutely came across "Iain Explains Signals, Systems, and Digital Comms" by absolute luck. Ian was my lecturer at Sydney University for a third year Electrical Engineering subject - Random Signals and Variables (i think that was the name of the subject!) over 18/19 Years ago. Ian was an absolute gun. Unfortunately, I can only remember 2 very good lecturers that I had over my 4 year Undergrad course at University. Ian was one of them! The rest were all shocking and no one bothered to go to the lectures because they lacked the ability to teach and could not speak English! Unfortunately, I did not achieve extremely high marks in Random Signals and Variables because the lecturer I had for Signals and Systems (a pre-requisite subject to Random) was absolutely useless with the damage already done! Brings back memories. I have been in the Power Systems Engineering field for the last 20 years, i have worked in a lot of areas like Protection, Earthing and Bonding, Commissioning and Project Management. Some advise for future students - consider a university other than Sydney University for an Electrical Engineering Degree.

I think that the three first rules can be replaced by the clockwise rule ! 🙂. When the current is going away from me then the magnetic field is clockwise. When the current is coming towards me Then magnetic field is counterclockwise. And vice versa ! 🙂

Iain thank you very much. This subject is a nuance that has befuddled me for years - I usually struggle with how to implement the RHR whenever it comes up. I copied your sketches into my reference book and I also 3D printed out a scan of a small hand I found on the internet. Now I am fully prepared! However, there is a 5th application I was wondering if you could add. In plasma physics we consider a "grad B" drift where there is no electric current at all (at least within a wire). You have the magnetic field direction and the "density" change in the magnetic field direction at a right angles to each other and this imparts a force on a moving charged particle in a particular direction according the RHR. Are you able to comment on this as well?

Fourth rule about motor action is F = q v x B Thumb in direction of v and fingers in direction of B then F in direction of open palm

Professor could you make a video on carriers and bands in your future videos. Am an undergrad and I can't wrap my mind around how multiple users fit into one single 5Mhz carrier for example.

I feel bad for all the EEs without hands... For the second hand rule, is it not just easier to use Fleming's left hand rule?

Are you using conventional current or the electron-flow current?

why is right hand rule different when there's a magnetic field inducing current?

Hello, quick question. So I saw this tutorial (timestamped): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vcStzn55MG0.htmlsi=eTDhqLbhss2HR1nE&t=310 And i was unsure because it seems like the explanation was opposite of what you said here (they have field lines out of the page, but current is flowing CW). Just making sure, but is it that: For a normally flowing magnetic field, say out of the page, current is created CCW around a loop of wire. However, for a magnetic field that is increasing in strength out of the page, current is induced CW Is this correct? I guess my questions are: -is the RHR only valid for the first derivative/velocity of the magnetic field lines? (and not for second derivative/change of velocity effect) -is the word "induced" specifically used for creation of current from a change in magnetic field as opposed to a constant magnetic field? -so the kind of "result" from a change in magnetic field vs the "result" from a constant magnetic field have opposite directions, correct? Is that kind of similar to the concept of momentum/inertia resisting a change in state? -If you wanted the net magnetic field at any point in time, would you have to then examine both the first and second derivatives of the magnetic field equation? What about the third derivative of the magnetic field? Why do we not generally study it, and what are its effects? Thank you very much as always.

Thank you! A question though; For example 3 we get that B ia pointing upwards and thats the direction of the magnetic field. Does that mean that there is a south pole at the top end of the coil? Just really struggling to find the connection. Thanks!

The fourth use may need to be redone more clearly. Slightly confusing. And this is coming from a physicist, lecturer and teacher. Cheers!

hazzah

Your drawings are good

Thanks!

thank you!
