A magnet rotating inside a coil of wire will induce a current in the wire. Disassemble a bicycle generator and that is what you will find inside, a magnet attached to the input axle surrounded by a coil. The current generated will be alternating current because the magnetic field reverses every 1/2 rotation. Frequency will depend on the speed of the input axle, which is of course dependent on the speed of the bicycle itself.

What components are present in every nuclear power plant that generates electricity?
(Nuclear reactor) creates heat Water heated to create pressurised steam (Boiler) Pressurised steam released via turbine chamber (Steam Turbine) translating motion to turbine shaft. Turbine shaft windings rotate inside magnets to generate electricity (Generator)
How is wind energy utilised?
wind turbines are placed to make use of wind energy, in the wind turbine an alternator having large gear mechanism is fixed , when the wind blows, the turbine moves, which in turn forces the gears to rotate, which in turn moves the alternator to generate electricity.
What is torque equation in DC generators?
generally generator is used to generate power whether it is AC or DC . to generate energy it is necessary to rotate armature at constant speed . it can be achieved by motor or any engine.
How is hydroelectric energy converted to electricity?
in an hydrolectric plant there are turbines in the bottom then the water is made to fall from a great height which causes the turbine to rotate and producing electricity in same way as done in rotating dynamo
How does a hydroelectric dam generate electricity?
A hydro dam works by taking the energy of water flow and converting it into an electric voltage. The water is regulated through a series of water turbines. The water flows through the turbine, pushing the turbine blades causing a rotation to a shaft. The shaft is then attached to an electrical generator. Inside the electrical generator, magnets are rotated around wire coil inductors which cause a voltage. ---- The word 'hydro' means water. When water is stored in a reservoir by construction dam, the stored water will have gravitational potential energy. When water is allowed to flow down this PE is changed into kinetic energy. This KE will make the wheels of a turbine to rotate. This mechanical energy ie rotational energy is changed into electrical energy with the help of magnetic field. This phenomenon is known as electromagnetic induction, first found by Michael Faraday. This is how hydro power is changed into electrical power. ---- The energy in moving (falling) water, is supplied by gravity, and the moving water has kinetic energy. This mechanical energy is applied to turbine blades, and the turbines turn electric generators to generate electricity. ---- Hydro power is generated by using kinetic energy from flowing water to turn turbines in generators. Turbine is moved with flow of water and this is coupled with generator to produce electricity
How do you generate electricity using magnets to power Christmas lights?
To generate electricity using magnets to power Christmas lights, you can use a generator that converts mechanical energy (rotation of the magnets) into electrical energy. The generator consists of coils of wire that rotate within a magnetic field created by permanent magnets. As the coils rotate, they induce an electric current that can power the Christmas lights.
What are large wheels that rotate the magnets of a generator when pushed by steam wind or water?
Those are called turbines. Turbines are used in generators to convert the kinetic energy from steam, wind, or water into mechanical energy that rotates the magnets to generate electricity.
What do windturbines do?
Wind turbines rotate in a circle in the wind and generate electricity
What does a genarator rotate large coils of wire past?
Large Magnets, passing through magnetic fields which become electricity.
What is hydorelectricity?
Electricity generated by water flowing through turbines which rotate between `brushes` of magnets surrounded by copper wire, I think!
How do we generate electricity by burning fuels?
Water is boiled to create steam in a turbine. The turbine is made of magnets that rotate around coils of wire which induce an electric current. Another way is hydro-electric power such as a dam. As the water pours over the dam it spins turbines that create the electricity as described above.
Can a bicycle paddle be used as a turbine to generate small amount of electricity?
Yes, it can. But you will need a great amount of force to rotate it.
How do magnets work in washing machines?
Magnets in washing machines are typically used in the motor to generate the rotary motion that drives the washer drum. When electricity passes through wires wound around the magnets, it creates a magnetic field that interacts with the fixed part of the motor, causing the drum to rotate and agitate the clothes during the washing cycle.
What is the name of the big fans that create electricity?
Wind turbines are the large fans that create electricity by harnessing wind energy. They have blades that rotate and generate mechanical energy, which is then converted into electrical power.
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.
What components are present in every nuclear power plant that generates electricity?
(Nuclear reactor) creates heat Water heated to create pressurised steam (Boiler) Pressurised steam released via turbine chamber (Steam Turbine) translating motion to turbine shaft. Turbine shaft windings rotate inside magnets to generate electricity (Generator)
What do you need to generate electricity?
To generate electricity, you need a source of energy such as fossil fuels, renewable resources like wind or solar, or nuclear reactions. This energy is used to rotate turbines connected to a generator, converting mechanical energy into electrical energy. Transformers then increase the voltage of the electricity generated for efficient transmission and distribution.
