Fundamentals of Halbach Arrays

Thank you for this! I'm a Biochem major that has been researching table-top NMR spectrometers, which are starting to utilize Halbach magnets. I was trying to wrap my head around how the fields were rolled and directed into such a narrow field, and this really helps!

He still all of his fingers.

[@danielschroederministies]

LOL!

[@HeyChickens]

Once they are in an array like this and shielded somewhat by the material that encases them, the attractive force between the two arrays at any significant distance is very low. The whole idea with this type of array is to concentrate the field towards the center, so that doesn't leave a lot of the field for the outside.

[@michaelbuckers]

Electric motor's speed to torque ratio depends on its inductance, stronger magnetic field helps shift this ratio towards smaller RPM and higher torque, power is unchanged. With low RPM motor you need less (or none) gearing, so total drivetrain efficiency is higher, but the downside is that the shafts and the windings armature need to be made tougher and bulkier to handle all that torque.

[@ConversationswiththeAI]

Which is why distributed power as close as possible to contact patch while maintaining low unsprung weight is crucial in automotive.

I often use millimeters for small measurements, even though I live in the USA.

This is because the imperial system is so garbage and outdated it doesnt even include measures near this small so we kind of have to use millimeters, and we use centimeters a lot too. All arbitrary in the end though

A diamond saw blade (non magnetic) with an air jet to blow away the particles.

[@deluxeassortment]

A simple bandsaw and some cutting oil works just fine. Edit>>> I should say that with a caveat: Neodymium magnets are NOT easy to cut. They crumble easy. But most other magnets can be cut with not problem if you use the correct blade type (abrasive for ceramics) and plenty of cutting oil. I actually had a neodymium magnet pop like a firecracker once when trying to cut it with a hacksaw!

[@gristlevonraben]

Most magnets are created by mixing metal powders then slow baked in a mold or cast, then electrically magnatized after they are baked into the shape wanted.

Heating is a challenge, but so is breaking. Rare earth magnets tend to be pretty brittle. That's why it is generally worth it to just pay someone who has the equipment and practice to do it for you ;)

[@mundymorningreport3137]

He talkedfast. Wasn't it bending or rolling the adjacent field? The neighbor magnets push the field out and physically withstand a lot of physical pushback to hold it further out. Magnets only add field effects, they do not cancel. So if the North field is pushed out, the South field is pulled in with it.

Dear fellow viewers: if magnets are in the same orientation the reaching distance of the magnetic field becomes further but the gauss measurement is the same. In the hallback array the gauss measurement can be a little higher than just one magnet. And the reaching distance is the same.

[@wbeaty]

A ringlight with twenty LEDs makes twenty glowing stripes. (Rotate the ringlight, and the stripe-pattern rotates too.) "Ferrocell" isn't showing magnetic field lines, instead it's showing LED reflections from microscopic strings of particles in ferrofluid. It's much like illuminating some iron filings with a lighting strip full of separate LEDs. Yes, the iron filings will produce glowing reflections, but the stripes of light-reflection aren't "field lines." The actual micro-pattern of iron particles WOULD show the magnetic field shape. But all we can see is the optical "glints" or "highlights" caused by the curved strings of reflective microparticles. (It's much like the glistening highlights of shiny hair. We want to see the actual hair patterns, rather than only the curved glowing reflective highlights caused by the hair.)
