Fun fact - I just learned that most cheap rice cookers use a magnet to "sense" when the rice is cooked. Basically when rice is cooked, the temp of bottom of the pan will go up fast, the magnet gets DE-magnetized at that temp (about 114C I think) and turns off the main heat.

One of the neat things about ferrite magnet motors is that the motor stator magnet can be assembled into the motor frame before being magnetized. Takes a lot of work out of fighting with the magnetic attraction and repulsion during the assembly process. Once assembled, the assembled frame is dropped into an electromagnetic fixture, and then the field magnet material becomes actual magnets.

If you turn the magnetized iron bar east and west and tap the west side repeatedly, then you will demagnetize the bar. Separately, there is a paper over on my subs tack that talks about making more powerful magnets by changing the shape of their magnetic moment by spinning it in the magnetic field and/or spinning the magnetic field itself while magnetizing a material.

William Sturgeon was the inventor of the DC motor and the first electro magnet. Fascinating and largely overlooked, Born dirt poor near Kendal and apprenticed to his father as a boot maker. Eventually he ended up in the army at which time he taught himself to read, write and speak half a dozen languages. His passion became scientific experimentation and invented the first practical electric dc motor, communator and electromagnet.. Sadly he was before his time and although producing working models to display he failed to generate financial backing for what was seen as curious though interesting. He died a pauper and is buried just outside Manchester.

(It's because of the issue with Saturation that was explained in the video, field wound electromagnets can be made stronger than permanent magnets). So, This new magnet would allow for ~doubling the total available strength of the Permanent Magnet Motor (or generator) because it wouldn't saturate until a much higher value.

There's actually a different class of materials called electrets, which can be made to have a permanent electrostatic field (as opposed to magnets that can be made to have a permanent magnetic field.) Essentially, you take polar molecules (i.e., most organic molecules like plastics) which have an electric dipole moment, heat them, and then cool them in the presence of a strong electrostatic field, where they get frozen in alignment to the field. Afterwards, the material has a permanent electric polarization in the same direction. They're used to make a particular kind of microphone, among other applications.

Photons don't carry gravity, however, and the particle that does hasn't been identified yet by physicists. As far as we know, the only way for something to have an "opposite" effect on gravity would be for it to have negative mass, and we're not really sure if that's even physically possible, let alone how to create it.

It's not like a static/permanent magnet, but more of an electro magnet. It's partly about the materials, but more about the fast spinning. Fun fact (or likely probability), the inner core rotates independently, and at a different speed/rate and tilt than the rest of the earth. Interestingly, back in the 1930's, Edgar Cayce said that in 1936, there was an upheaval deep within the earth, that led to a difference in the axial orientation of the inner earth core away from Polaris (and thus the rest of the earth), and that these major, but gradual changes deep within the earth, would eventually lead to an increased warming trend (and a more geologically active earth as to earthquakes, etc), starting at 1958, especially at the polar regions, becoming obvious/overt by 1998. Also changes in the magnetic field would result from these changes, with either a polar shift *or a start of a new cycle* in the shifting/changes in same, happening by 2000/20001 time frame. Indeed, it was right around the turn of the century that the change in both the speed of polar magnetic field wandering and field intensity, dramatically started to speed up for the wandering and the field intensity weakening. (Cayce died at the beginning of 1945). From 2000 to now, we've lost more magnetic field strength than we did in many decades prior. But who knows eh?

If the generator system isn't fully matched, then one could build a more efficient generator system that could handle higher energy loads, and if that is the case, then yes, these magnets would help. Such public systems generally weigh cost vs efficiency vs the age old question, "is it good enough for the most part?". It the generator system has covered the needs for the area more or less well until now, then it is possible that there is room for improvement as population expands and energy consumption goes up. Generators are like an inverse process/operation of electric motors. Motors have a limit of energy they can handle before being overwhelmed, especially in terms of speed and/or intensity of cycles. It would make sense that generators also have a fixed limit as well.

Silly question does it change weight when it’s magnetised?
@spehropefhany4 ай бұрын
The energy changes so the mass would increase. Very, very, very slightly. I see 87J/kg for NdFeB, so divide that by the speed of light squared and you get something pretty close to zero.

I would guess not enough to notice. But it's not a silly question.

Even if the mass does not change measurably, it might change dimensions measurably, which would mean that the density could also change.

"Hey, Ferb, guess what we're buying today?" "A Rock Tumbler?" "Are you reading my mind?" "No, just watching the same video." By the way, the Curie point of a magnet is how Rice Cookers, and my covfefe pot both work. A Magnet holds the switch closed, and when it gets hot enough, loses its magnetism, and a spring, or gravity, then open the circuit. They are set for different temperatures, Rice shuts off at about 215F/101C, whereas my covfefe pot is probably about 180F/90C (Approx).

My covfefe pot doesn't do that. I feel like I need an upgrade.

Close, it is actually the metal pot that demagnetizes temporarily, and once it cools down, it regains its magnetic properties. Often when magnets themselves reach their curie point, they lose it permanently. "And I'm spent..."

So now, in 2024 I have not heard anything about the new iron nitride magnets. What happened ? The " if it seems too good to be true it probably isn't " rule kick in ?

Mixing iron and ammonia in tumblers. I feel danger. Putting earth's abundant metal with abundant gas in earth's atmosphere! Now what if it's possible to spellbind some enhancement spells 😂
