Vacuum engine - with magnetic brake - Flammenfresser

[barkeg050]

wow, cool! and the music too ;)

[randommagnum]

C'est le la force de Lorentz

[Armapax]

@randommagnum

Attention! les volants des moteurs doivent être non ferreux, c'est à dire non magnétique, ici ne laiton ou en alu.

C'est le Frein de Foucauld voir sur Wikipedia

[randommagnum]

@Armapax Je ne pouvais pas trouver 'le breake de Foucauld' sur Wikipedia.

Thats how a speedometer works...

Impressionnant!, la musique est bien choisie je trouve, "l'apprenti sorcier" de Paul Dukas

bravo

[Armapax]

et oui la musique c'est voulu :-))

normal ^^

Do you have a magnetic coating on the wheel? How much force is needed to slow it down?

[Armapax]

No, nothing magnetic on the wheel,

in French

"courant tourbillonnaire de Foucault"

[Jordankewl]

it's magnetic braking. it happens with aluminum. check wikipedia for good info on it

[frankensteinmoneymac]

@bitsurfer0101 No need for a magnetic coating....a magnet put beside a moving conductive surface (or vice versa) like aluminum or copper will cause tiny eddy currents of electrical energy to flow in the conductive surface, which resist the magnetic field. Try taking a powerful rare earth mag. just barely smaller than the circ. of a copper pipe. Drop it down it and it will fall in slow motion...a really cool experiement!!!

très belle démo
