WHAT THE FLUX IS UP WITH RELUCTANCE?

Reluctance is to magnetism as resistance is to electricity. This video goes into the math and concepts behind this not so tricky idea.

Loving your videos, drawings and the math workings. Any chance you could continue the videos on magnetism?

[@kevinclaypool6345]

This is a very dense subject that requires utmost concentration, honestly the music was very distracting and I wish it weren't in the background.

[@khaliffoster3777]

Ok, base on understanding of ratio of reluctance to permeability so reluctance is base on high absorbility of energy field to saturation, so the iron will absorb high speed after the electricity cut off, so iron is speed captance and the higher speed captance, the better time rate. So, like a glass with water, so the glass is empty so you pour the water, so the glass is a resistance to electricity, so glass is resistance so hold the water, so the energy will go high, then absorb, so put low sponse or high sponse, so which sponse faster, per time, so iron has higher absorbility rate so iron is better. So, that is higher reluctance which the magnet field will absorb in high speed in the mass after the circuit is cut off. The magnet force or magnet force, mmf. Well, since the electricity is first which interact the resistance so it will react, so thru react it will cause magnet field so the magnet field is being absorbs, so the magnet is use as a mover or a store for electricity field, so like a battery, so when the battery is used, the volt will be gain to the load since a battery is activity, so the electricity is activity which it change from one to another like resistance to volt, so magnet within the mass will react. All mass has magnet within so waiting to react, so mass is captance that hold the energy.

thanks again Chad, im just preparing for level 3 and your a great help, idk whats going on my buddy only sent me worksheets but your videos are helping alot

[@kelsie9912]

Thankyou so much! This really helped me get more of an understanding and also was great practice with using the formulas and interchanging them to find the missing information. My school online content gave me next to nothing to practice these calculations. So thank you!!

[@djchameera]

keep up the good work. many thanks

[@jacquelynmrozowski8593]

Hey chad love the vids! was wondering if you could make one to help out with Determining CW or CCW rotation for gennys and motors, as well as figuring out if they're diff. or cum. , would appreciate it lots! cheers

[@rickdeckard1075]

defluctance and isorelucticity are inverse phenomena, according to modern Farvous Theory (the neo-extended classical Farvous Theory)

[@danssimoes9083]

Chad, in just a few seconds I could understand what reluctance is. Great comparison.

[@DerekWoolverton]

What are the properties that affect Rm? If I made a loop twice as big, how would it effect Rm?

[@stuartvasquez6404]

Hey brother I’m sorry to bother you but I was just wondering my local IBEW isn’t taking applications at the moment and even if they do I don’t know if I’ll be able to get in. Is there any other option for me to become a licensed electrician without the IBEW? Could I get the same sufficient schooling somewhere else without their apprenticeship?

i hope u can make a video on transposing...

[@EnterGenericUserName884]

Why did you stop making videos two years ago? The videos on this channel are all interesting. In case anyone's reading this: please keep going!

[@MRElectrics]

good

cheryl at bcit was just speaking about you spear heading online learning and getting BCIT to get with the times

[@RomansapienMVision]

I did not know Pete Davidson's uncle know so much about magnetism

[@Dr.JustIsWrong]

I just wanna know where to get metglas.. 🤣

[@phasepanther4423]

The math shown here is easy. But what is reluctance? Why does it exist? Is it like capacitance or inductance that store energy in a field temporarily? Is it like resistance that uses energy and let's it off as heat? What exactly does it resist if magnetism does not have anything flowing? How does it relate to permeance? Can someone please help? I have an exam coming up and I can't focus on my work because I'm unable to understand this which was a footnote in my book. If they'd left it as analogous of resistance in an electrical circuit it wouldn't have been so bad. But they had to add that it shouldn't be taken too literally as the energy is not used up but stored. And now I'm totally lost, clawing my way down the rabbit hole of magnetic circuits trying to understand what exactly happens.

[@james77011]

Reluctance is like resistance in an electrical circuit. Reluctance opposes the creation of magnetic lines of flux

[@phasepanther4423]

@@james77011 Don't worry I eventually figured it out. That vague answer was the exact thing about my textbook that annoyed me. It's like resistance, but it's not. It is to inductance what batteries and cells are to capacitors. With magnetized materials keeping the energy in their fields long after current is removed.

[@james77011]

@@phasepanther4423 oh well 🤷‍♂️😒

[@phasepanther4423]

@@james77011 My apologies. I did not mean to dismiss your assistance. But there was no explanation of what happens to the energy. A hysteresis loop is the best visual representation. But also understanding how ferromagnetism works.

[@Dr.JustIsWrong]

So, your first example is basically 'measuring' the reluctance actually used and giving it a calculable value. Second is merely 'counting' loops. And the third for calculating amps of an 'existing' unit. These seem to be 'academic exercises' _(contrived homework)._ Merely mathematical manipulation with never less than 1 unknown. Any variable may be used _(e.g. __2:48__ a=b/x)._ In other words, this is math, not magnetics. Fair enough, but DIYs learn new nothing here..
