Then, due to force on pivoting, it turns. But, then we're causing strain on the material of that is to pivot around. So, this builds up heat and wear&tear to heavy degree. To prevent this, we can say we build this coil in a circular manner without making the coil touch the ground due to obvious reasons

you seem don't get it,the main problem with "coil gun"motor is that if the ferromagnetic projectile (welded firmly with the rim of the wheel - so the heat or worn out problem is not major) run into a CIRCULAR barrel,through many magnetic hoops, the rate it lose its saturation will increase significantly compare to a linear trajectory( if we use one projectile and make it run through the drive electromagnets again and again) that's why the coil gun is designed as linear electric motor and it should not(or maybe never) be made circular. It's true that there are various problem with energy dissipation,but they all come from electrical resistance and resistive losses, not the material.Nevertheless, i must agree that it's just similar to a normal electrical motor if we use it as above( with a weird rotor ^^).
Now, we come to the main part.First of all, i'm really surprised that making airtrek processes to the debate of technical details o_0 supposing that we have a mini engine powerful enough for you guys, and you put it in your shoes, what would happen when you begin to move? you must lean forward so that the torques of gravity force, inertial force and other resistance forces can balance.The net force affect your spinal column and the angle between your body and the direction depend on the acceleration of the AT, so if the motor in it accelerate like a car, your body will not sustain the impact (it's the obvious reason why a powerful engine is always used in a transport that provide us a seat 🤣 )
So, to what extent will the acceleration not harm us? I think it's about 5 m/s2 (which you can get by using normal rollerblade, lol)

You know, I didn't even think of the interference when I was writing that, but you are quite right in pointing in out as a major flaw. But you could always shield the interference (to a degree). Are we creating a circular particle accelerator? It's clearly possible, not at a small scale with today's tech tho.

And on counter point, if the coil is going to apply strong enough force to move a person at a "good" rate in just one direction, the total amount of skewed force will be quite high, so it's not neglectable at all. Quite possibly greater than the spinning force it can even apply (depending on it's figure). Especially if you are planning to use it for long periods of time.
Tbh, I think this part is far too freq neglected in high school physics (not implying that anyone is in high school, just a side note).

btw, typical person can handle upto about 5g's = 49m/s^2. But even more likely, I think the person will just fall back on their butt as the skates propel forward... And there are tons of valid reasons here already where it would fail even if AT were possible to be made, people just turn a selective reading tho.

If we ignore wind resistance and every other possible resistance (like flying bugs) 🤢 (which we really shouldn't), we could at least travel at bullet train speed. 🤣 Bullet trains can travel much faster, technologically, it's just that ppl start passing out/ dying if it goes any faster.

I thought it was more like a 1000. What's ur point tho?

none. i was just reading them all and theyre exactly the same.
it would be cool though

^_^ the projectiles in a typical cyclic accelerators are charged particles, not ferromagnetic, so losing saturation is not a problem(anyway, did i say that it's impossible to make circular accelerators or the skewed force when moving is negligible ?)

well, i said clearly that we have to lean forward to keep balance when the skate propel forward and WON'T FALL, and whether we can keep that balance or not depend vastly on the ACCELERATION.
If resistance is neglected,and the acceleration = g (9.8m/s2), the angle (between the body and the road)is 45 deg, net force is 1.4 * your weight , if a = 5g that angle = 11 deg 😲 total force is about 5.1*your weight 😲 , i really don't know how long we can move with that tension on the spine,seriously, if you know,plz tell me !

And i will say it again, powerful engine is not something you can put in your shoes and move forward, but small device with other functions is ok

did u guys made these, or still in progress, if so i would love to isjoin in this project

p.s. who cares if they are illegal, thats the fun of thise and we would make them our selves so only we have them not stores
