How fast does a power plant generator spin?

What causes a magnetic field to be set up around a wire?
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.
Why there is power dissipation in field winding whereas it is negligible in armature winding?
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.
How do electromagnet work?
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:)
How fast does a propeller have to spin to lift a man off the ground?
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.
What is fast in spin and fast out spin in cricket?
There is no such bowling style as 'fast in spin' or 'fast out spin in'.
How fast does a volleyball spin?
Fast
What does an electromagnet do when it is connected with wires and a motor?
When an electromagnet is connected to wires and a motor, the electromagnet generates a magnetic field when current flows through the wires. This magnetic field interacts with other magnetic fields in the motor, causing the motor to either spin or generate motion depending on the design and configuration.
Can windmills kill you?
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 ;)
When was Fast Japanese Spin Cycle created?
Fast Japanese Spin Cycle was created in 1994.
Do tornadoes spin slow?
No they spin very very fast
How large and fast is are hurricanes?
they spin and move fast
Turbines spin generators which produce what kind of energy?
Turbines spin generators that produce electrical energy.
How do you use electricfan?
The motor has a coil of wire that is an electromagnet. This causes the motor to spin, turning the fan blades.
Why does the coil have to spin in a generator?
A coil has to spin in a generator to produce electricity.
What device uses an electromagnet to change electrical energy to kinetic energy?
An electric motor uses an electromagnet to convert electrical energy into kinetic energy. The electromagnet creates a magnetic field that interacts with a permanent magnet, causing the motor to spin and generate mechanical motion.
