We're sieving the material, we're using magnets, we're using air classification.

But with the pendulum, it allows me to manifest these invisible forces that are holding the magnets up.

The equilibrium rotation rate varies directly with the flow velocity and inversely with the distance between the magnet and the duct.

A current was allowed through a wire suspended from a pivot above the magnet and dipped into the mercury.

Copper has been used in electric wiring since the invention of the electromagnet and the telegraph in the 1820s.

The leading theory suggests that lodestones are magnetized by the strong magnetic fields surrounding lightning bolts.

Origin The process by which lodestone is created has long been an open question in geology.

In this case it is possible to measure either the torque on the magnet system or the angular velocity at which the wheel spins.

Schools named for Pearl In May 2007, the Communications Technology Magnet School at Birmingham High School was renamed the Daniel Pearl Journalism and Communications Magnet.

And so we can accurately if the magnet is big enough, and your resolution is high enough you can actually detect all of the proteins in the body and start to get an understanding of the individual system.

Research has revealed that on the comparatively small area of the mountain there are 1,500 species of higher plants, 500 species of fungi, 500 species of algae, 326 species of mosses, and 200 species of lichens.

A current is induced in a loop of wire when it is moved towards or away from a magnetic field, or a magnet is moved towards or away from it, the direction of current depending on that of the movement.

And we thought this was a very interesting comment on America, and a kind of self serving, not my responsibility kind of phenomenon.

Approximately 96 tonnes of superfluid helium 4 is needed to keep the magnets, made of copper clad niobium titanium, at their operating temperature of , making the LHC the largest cryogenic facility in the world at liquid helium temperature.

TS Well, like the magnetically levitated objects like that silver one there, that was the result of hundreds of experiments with magnets, trying to find a way to make something float with the least possible connection to the ground.

History of theory When William Gilbert published de Magnete in 1600, he concluded that the Earth is magnetic and proposed the first hypothesis for the origin of this magnetism permanent magnetism such as that found in lodestone.

It's sort of like sobering up.

I think that's a new species.

A dolphin is a kind of mammal.

It is an endangered species.

What kind of music is this?
