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 spinning jenny work?
spinning
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.
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.
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.
How does a bike dynamo generator work to produce electricity while cycling?
A bike dynamo generator works by using the movement of the bike wheel to spin a magnet inside a coil of wire. This spinning magnet creates an electric current in the wire, which is then converted into usable electricity to power lights or other devices on the bike.
Would a generator work if the permanent magnet rotate rather than the coil of wire?
I really don't know. :D
How does a bicycle magnet work to generate electricity?
A bicycle magnet works to generate electricity by creating a magnetic field that interacts with coils of wire in a generator. As the magnet spins with the movement of the bicycle wheel, it induces a current in the wire coils, producing electricity.
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 permanent magnet generator work to produce electricity?
A permanent magnet generator works by using the magnetic field of permanent magnets to induce an electric current in a coil of wire. As the magnets rotate, they create a changing magnetic field that causes electrons in the wire to move, generating electricity through electromagnetic induction.
How does an electric generator work to convert mechanical energy into electrical energy?
An electric generator works by using a magnet and a coil of wire to convert mechanical energy into electrical energy. When the coil of wire rotates within the magnetic field created by the magnet, it generates an electric current. This current can then be used to power electrical devices.
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.
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.
Can you make electicity from a magnet?
No, magnets alone cannot generate electricity. However, when a magnet is moved near a coil of wire, it can induce an electrical current in the wire through the process of electromagnetic induction. This principle is the basis for how many electric generators work.
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 must you have for an electromagnet to work that you don't need for a regular magnet?
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
