A spinning electromagnet does not produce power without other components that you need to specify.

Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
There are losses associated with both, but I don't think that's what you're getting at. The power applied to the field winding, typically on the rotor of a generator, is used to turn the field winding into an electromagnet; This electromagnet is forced to spin, which induces a current in the armature windings. This induced current is the power output from the generator. So a little power is lost/used in the field winding to convert the kinetic energy from the turbine into electric energy.
If a wire is wrapped around a ferromagnetic material (those which are attracted by a magnet) and a current is flown through the wire, the material behaves like a magnet. This phenomenon is known as electromagnetism. The electromagnet can attract other ferromagnetic material just like any magnet. Usually a soft iron-core is used for good results. By such a phenomenon you get a temporary magnet whose magnetic property can be switched on or of by a switch! You can try this at home by wrapping a wire around an iron-nail and using a battery for current.Hope this helps:)
That's a difficult question to answer. First, in the sense that a propeller is really an airfoil, it does, in fact, generate lift. However, the concept of lift with respect to aircraft, generally refers to the vertical lifting force, and this is produced by the airfoils (wings) and not the propeller. The propeller produces forward thrust which, when sufficient, generates the speed necessary for the wings to produce lift. So, back to the question: A propeller needs to turn fast enough to produce enough forward speed for the airfoils to produce sufficient lift for the aircraft to rise. The RPM necessary to do this depends on the size and number of blades, the power of the engine, the weight of the aircraft, and a number of other factors such as airport elevation, etc. Sorry this doesn't exactly answer the question, but hopefully it will help you craft a more specific question that can be answered more accurately.
There is no such bowling style as 'fast in spin' or 'fast out spin in'.
It causes the motor to spin.
Fast
If the blade hits you in the head. Lol. What a funny questions. Can the electricity the produce kill you? Sure, if its big enough. Can the blades kill you when they spin? Sure, if they spin fast enough. Just like everything in life, if its moving fast enough - it will kill you ;)
Fast Japanese Spin Cycle was created in 1994.
Turbines spin generators that produce electrical energy.
No they spin very very fast
The motor has a coil of wire that is an electromagnet. This causes the motor to spin, turning the fan blades.
they spin and move fast
A coil has to spin in a generator to produce electricity.
It can spin pretty fast. On impact, it can break a lot of things, including the yoyo.
Dancers Spin Fast Bcus They Have Lite Shoes Wiv Not Much Grip *AND* Bcus They Are Trained
