Will a generator work if the wire is not spinning but the magnet is?

Yes. One winding/magnet must spin. Some generators have two windings, one is stationary (the stator), and the other spins (the rotor). One of these windings is energized, making it an electromagnet (called the field winding). In most generators of this type, the field winding is the one that is spinning. This is due to the fact that the stationary winding is the actual output of the generator, thus experiences high currents - and it is easier to pass these high currents through stationary busbars to the grid as opposed to rotating equipment.

How do you design wind turbine?
get a stick n a propeller n fix them the way that they make electricity is by moving an magnet inside coils of wire so attach a magnet to the inside of the propeller and wrap coils of wire around the magnet but with 1mm of space between. attach both ends of the wire to an applience e.g a light and it will work
How does a dc generator work?
By using a gas engine to drive a dc motor. Motors are cool in the way that if you give them power they will spin and if you spin them they will make power. There is a ball of coiled wire in a motor and when it spins the magnets in it try to resist the spinning but if it succeeds in spinning then electrons will be pushed through the coils by the resistance of the magnets and ultimately through your electrical appliance's.
How does a spinning jenny work?
spinning
What is dc separately excited shunt generator?
Either or both can be separately excited. To generate voltage you need a big magnet( the field). Most generators use an electro-magnet. Now the electro-magnet needs a source of power (electricity). We could use the generators own output to excite the field (magnet), this is called self excitation. The problem with self excitation is that we have to wait for the generator to turn and start generating, also to start generating (Building up) there must be some left over magnetism from the last time it was run (called residual magnetism) or not even a little voltage will be generated to start the field current flowing. To solve these problems we could use separately excited. This means we must have a separate source of power to excite the field to produce the magnetism. Sometimes a battery or gasoline driven generator is used to excite the field of a very large generator to get it generating and then we can use some of the generated output to either recharge the battery or switch over to from the battery. In any case we have adjustable control of the generator all the time. This is why most generators are designed to be separately excited. And that is why you car has a voltage regulator. It wakes up the alternator when the engine is started by separately exciting it (the field) with the battery and then regulates the output voltage of the alternator as the engine changes speed with the driver's commands from the gas pedal.
Can you use a car as a backup generator for a house?
creative, and nice. Yes, if you some how rigged it (the wheel) up to a alternator/generator and into a transformer for home supply. you would have to jack the car up, or prop it up somehow, attach a generator by belt or welding, wire the generator to some capacity and then to an output transformer. Any motor can be made into a generator when attached to a power generation source, such as a alternator. DC MOTORS WILL NOT WORK. POLYPHASE INDUCTION MOTORS WILL NOT WORK AS THEY RELY ON TWO INPUT PHASES TO OPERATE AND CONTAIN NO MAGNETS.
Would a generator work if the permanent magnet rotate rather than the coil of wire?
I really don't know. :D
What produces electricity by spinning a magnet in a coil of wire?
A generator or alternator. If the magnetic field is permanent, the current produced from the coil will be alternating current. AC. Alternators usually work the other way round. The magnet is spun inside a coil of wire. The power is taken off from the stator. The rotor is an electromagnet, fed via slip rings on the shaft. The strength of the magnet can be varied and controlled externally, to control the output voltage.
How does a dc dynamo work?
It uses a permanent magnet which is rotated by a crank. The spinning magnet is positioned so that its north and south poles passed by a piece of iron wrapped with wire. It was discovered that the spinning magnet produced a pulse of current in the wire each time a pole passed the coil. Furthermore, the north and south poles of the magnet induce currents in opposite directions. By adding a commutator, it is possible to convert the alternating current to direct current.
Do power stations work with a wire and magnet?
Some power stations do work with a wire and magnet but some others don't.
Can a permanent magnet solenoid be modified to work like a permanent magnet linear generator?
yes - need to run electricity through it to make it a linear magnetic generator.
How to make magnetic power?
A note about terminology - magnetic energy is the energy stored in a magnetic field. I have never heard of magnetic power. However, I assume you are asking how to get electrical power from magnetic phenomena. The way this works is directly from maxwell's equations. Faraday's law says that the rate of change of flux through a loop (field through loop times area of loop) is proportional to the electric field around that loop, which is proportional to the current, if the loop is a conductor. The generator works by spinning a permanent magnet near a loop of wire. As the magnet spins, it induces current in the loop of wire, which can then be made to do useful work. A note about energy conservation: when the current in the loop is induced, it is always in such a way as to attract the spinning magnet, so the external agent has to do work to resist this.
How is electrical generator work?
An electrical generator is a device that converts mechanical energy into electrical energy. The fundamental principle behind its operation is electromagnetic induction, a phenomenon discovered by Michael Faraday in the early 19th century.
What do solenoids do?
work as the current carrying coil-of wire on and acts like magnet when conductor flows
What does solenoid do?

How does an electric fence unit work?
A generator runs electricity through a wire thus electrifying it.
Electric current is produced when a spinning shaft rotates magnets inside a generator?
The process in which electric current is produced when a spinning shaft rotates magnets inside a generator is referred to as 'Direct Current'. It is not expected to work by the normal standard physics model however some people claim it is just.
How do you create electricity using magnets. Please say this on a sixth grade level.?
In early physics and electric experiments, a fixed magnet with poles emenating laterally and spinning, were placed inside coils of wire so that the magnetic field of the magnet would pass through the wires. This produces a voltage at the terminal ends of the wires and if a resistance were placed across the terminal ends, a current would flow according to Ohms Law. I=E/R. You can made such a simple device by making a coil of wire with many turns, say about 100 and then suspend a magnet on a string that passes through the coil. If your magnet is strong enough and you coils are many, you can light a light connected to the wire ends by pulling the magnet swiftly up through the coil of wire. Any easily bent wire will work. It can have insulation which is really best because the coils will not short each other out. Try it!!! Electric Alternating current(ac) generators today produce a magnetic field by running a current through the windings of the rotor, the part that rotates. There is no permanent magnet involved.The stator or stationary part of the generator has the coils of wire that then produce the voltage. The electric motor works just the opposite.
