Current designs for maglev trains rely on electromagnets, since nobody has been able to make a permanent magnet strong enough to lift the weight of a train.
That is because a permanent magnet's maximum strength is dictated by the material it is made from, while an electromagnet's strength depends on the current passing through it.
The 2.5-liter inline 4-cylinder gas engine and permanent magnet AC synchronous electric motor in the MKZ deliver 191 net horsepower, a modest amount of power for a 3, 752 lb vehicle.
This will be the first commercial wind farm in the U.S. to deploy, at scale, turbines that use permanent magnet generators tech-speak for evolutionary turbine technology that will improve efficiency, reliability and grid connection capabilities.
This means that when a drop of liquid is mixed with a suitable solution of paramagnetic ions, which become magnetic in the presence of a permanent magnet, it will be pushed to where the field is weakest, and stay there.
"You'd have little packets that had this powder in it, you'd fill up your pitcher of water, you'd dump in the powder, stir it up, let it sit for a little bit, and then you'd have a permanent magnet that draws all the minerals down towards the bottom of the pot, and then you pour off the relatively clean water, " he said.
