_You can’t break a magnet in half…you get just two magnetic dipoles.”_ The inquisitive ones of us learned this by breaking our experimental magnets in half several times. Other students then did so. The teacher was not pleased. Should have taught us that lesson before handing us the school’s new magnets.
Let's suppose a 10v power supply at 2 amps, with 10 copper wraps and a steel core. Do I need a magnetometer that's calibrated for 0 - 200 millitesla? Or something that measures in 0 - 200 gauss?
The field direction around a long straight conductor is circumscribed which never points to the conductor. It arises from a different effect from the field of a PM where the B field [compass] points to the magnet poles where they emanate/terminate. A coil/solenoid mimics a PM through a geometric construct but that is only a trick/artifice.
thx for the video i just have a question regarding how to place the Tesla meter prob to measure the magnetic field inside the solenoid, the way inside the video, the magnetic field or even the solenoid is perpendicular to the prob, correct? how about if i place the prob not perpendicular to the wave or the solenoid. will i be getting the same magnetic field measurement on the Tesla meter?
That was one of the best of thee best explanations of the right hand rule that I have seen in all of the online forums.I would love to see this experiment done using DC in an digital IC circuit to detect data in the EMF radiation.
My search to get this video was "How to efficiently make electromagnetic force go somewhere" and I am still wondering, reason for me wondering is because of dead space's kinetic module, to lift heavy objects that a person could not ordinarily move..... So yeah
True. You'd have to stretch the slinky and wrap your ferromagnetic core with some cling wrap.... it would suck, but it would work. More interestingly: Would the shape of the wire significantly affect the flux density at higher frequencies? b/c most electromotive force would be on the outside of the wire, right? idk. probably not significant... but it's a thought
Dear Paul Andersen, Thanks for kind class,I have used Fi=BA, and d(u,v)=udv´+vdu.and equalizeit to 0, then D inside sol.=2 l,l is sol.legth,missing second derivative to check if is a max or min. Formula 1 uses D piston=2 l,l beng stroke.If you please tell me what is ocurring with plunger displacement? lets assume plunger ferrite,low remanence,length is h,and solnoid legth is l/2+l/2=L,what is plunger stroke between what distance between L,fom de middle? or from 0? If you please, I am behind a double acting, 2 solenoids in series,I undertood you that N moves from cero B grows?Thanks a lot,Kind Regards JOhann Wegmann
Professor, what if the solenoid is made of a hollow tube completely filled with ferrofluid and with both ends of the tube connected and looped through a high-speed pump moving the ferrofluid inside the tube, will the ferrofluid filled solenoid produces a magnetic field or force?
Quick question Mr. Anderson(or anyone who can clarify this for me). In the first few minutes, when you drew an arrow vector from South to North on the magnetic dipole to visualize the direction of the magnetic field, isn't it supposed to be the other way? I thought that magnetic field lines were conventionally drawn from North to South. Thank you.
The right hand is used for the conventional current whereas the left hand is used for the electronic current, and in the both cases the four fingers ultimately point to the same force direction.
Is right hand rule for conventional current flow or electron flow?
Thank you

What books 📚 would you recommend to read about this further? I like physics but don't like the technical language.
I wonder how in a transformer on the secondary it is one wire but labeled as ac .it seems like it would short it out at the base of secondary windings
"It seems magical, but its simply a magnetic force"? The word magical = magnetic force.
As always great video!

how to calculate magnetic force inside the solenoid
That was one of the best of thee best explanations of the right hand rule that I have seen in all of the online forums.I would love to see this experiment done using DC in an digital IC circuit to detect data in the EMF radiation.
Sorry to tell you but the experiment in the beginning has actually nothing to do with the explanation of the right hand rule....

buds a slinky will not work as a solenoid because the wire is not insulated
True. You'd have to stretch the slinky and wrap your ferromagnetic core with some cling wrap.... it would suck, but it would work.

That's a coil not a solenoid, a solenoid has a set of contacts

I will have to watch this again, thank you very much for sharing.,
very helpful, thank you :D

Yeah what you said
lol, "seems magical but its SIMPLY magnetic force" ... ya, magnets! how do they werk?!
Vertical =core
It's not "copper wire" its a pipe.
What is the name of this software, please?
WHICH ONE IS THE RIGHT HAND!!!
The right hand is used for the conventional current whereas the left hand is used for the electronic current, and in the both cases the four fingers ultimately point to the same force direction.

Well we can measure magnetic fields but not gravity.....think we can all see here what the true driving force behind "gravity" is.
U make me wanna science
