this is how we will one day time travel.. eddy currents
6 years ago
who's Eddy
6 years ago
Eddy currents are currents induced in conductors, when a conductor is exposed to a changing magnetic field due to relative motion of the field source and conductor; or due to variations of the field with time. This can cause a circulating flow of electrons, or a current, within the body of the conductor. These circulating eddies of current have inductance and thus induce magnetic fields. These fields can cause repulsive, attractive, propulsion and drag effects. The stronger the applied magnetic field, or the greater the electrical conductivity of the conductor, or the faster the field changes, then the greater the currents that are developed and the greater the fields produced.

sorry pedrobeara but....WHAT?
6 years ago
In a fast varying magnetic field the induced currents, in good conductors, particularly copper and aluminium, frequently exhibit diamagnetic-like repulsion effects on the magnetic field, and hence on the magnet and can create repulsive effects and even stable levitation, albeit with reasonably high power dissipation due to the high currents this entails

Forget it tool, they'd never take you alive. Not with all those guns.

It's not magic, that tube is really 10 feet, not 1 foot. Well, in "man measurements" anyway.
6 years ago
What the fuck are you talking about?
6 years ago
Man measurements. He says it is 10 inches when it is really two.

What the fuck are you talking about?

is this where someone makes a 'like you could feel either' comment?

I was gonna say leave the measuring to the guys but that works

Sorry, didn't know you all had no sense of humour
6 years ago
we do when something is funny

Is that an alternative way to spell humor?
i see it fairly often.
6 years ago
humour is british. like travelling (traveling), theatre (theater), and wog (towelhead).
6 years ago
Canadian. So we spell things such as humour, neighbourhood, shopping centre, fuckin eh.

im a canadian... i just dont bother trying to spell right

spelling is highly overrated, it is all about content
6 years ago
There are major corporations and companies in the US that send their new hires to spelling school so they don't look like retards when responding to customer emails. These recruits are products of the public school system and colleges they borrowed thousands to attend. Companies spend thousands to educate them (after they've payed for and received a diploma that means nothing) on the basics just to get them up to speed. Would you also propose that factual knowledge is overrated and only the content matters? Consider that for a moment.
