Physics Help : How to Make a Magnet Levitate

[jms4323]

so your telling me that if you make a hexagon of magnets and coil on the bottom of a skateboard.... I could make a hover board.... O.o

[kingpiccolo101]

get a large flat magnet and a magnet and watch your magic happen!

boring :p talk about mortal kombat ooooooooo mileena vs kitana

[cllai777]

sorry!"future"

[cllai777]

wow, you are Marvelous! hope to be your student later n futuer

[radisav]

what material is used for coil?

[kingpiccolo101]

@radisav probably copper

[MrGhirbo]

fake ! it only repels if the electrict current goes in 1 direction ...

[TheMadScientist01]

Impossible to make levitation without anything guiding magnets? Well look at these vids:

/watch?v=uW7Rd6Nn2-Y

/watch?v=M5xVPJUdTHk

/watch?v=-vwkH2DdV4I

/watch?v=5s-wLNhRxzs

put 2 magnets in a clear tube.....no coil/battery needed!... :)

[Avenrei]

Why is it harder to use permanent magnet like he said at 0:50

[SGTRandyB]

No energy needed.

[SGTRandyB]

Um....Professor, how bout simply using 2 ring magnets? 2 large neodymium ring magnets at N52 gauge would hold a car suspended along a single vertical axis.

[esthermlaw]

The only thing you missed was at 2:20 - the balance-point is the balance between the repelling force against the aluminium ring and the "pull" of gravity on the aluminium ring.

agree with EliasOwnage!! if u were my teacher i myt be a gud scientist though :D

[pkREX24]

How strong does the power source have to be?

[pkREX24]

how strong does the power source have to be?

[khoaanhtran01]

@pkREX24 the power source varies depending on how much weight you are trying to levitate. heavier object requires a stronger force while weaker object requires and lesser force. just hook the wire into and adjustable psu

[DemonHeart66]

three people could not levitate the ring

[TanyaRossLive]

If some one would use 4 1000lb (4x1000=4000lb) electromagnets on the floor and 4 50lb (4x50=200lb) Neodymium Magnets on their shoes, is he able to levitate? Considered that the electromagnets are placed, so that its stabilize the human?

[Batina041]

His explanation was very good,easy to understand but I was expecting two permanent magnets levitating.But this works to.

[EliasOwnage95]

you're a true teacher , wish u were my teacher in physics.

[uday932]

if there is no metal rod to hold it what will happen

[salolamilainen]

I am trying to build a ring launcher for my AP Physics exam. I want it to be powerful enough to launch the ring several meters high. Can I get any suggestions as to how to do this?

[Trebledeaf]

@salolamilainen he says the balancing is were the coil will stay levitating., so creating a lager charge would be the case wouldnt it? i actually dont know', heh

[TheRationalPi]

Lenz's law covers this one. The changing magnetic field in the bar induces a current in the aluminum coil that opposes the force that induced the current in the first place.
