What role do magnets play helping a generator create electricity?
Magnetic generally generate electricity just by moving the magnet. Although you can't actually "create" energy, by rotating a magnet, you generate kinetic energy.
They produce a magnetic field. The moving wires cut this field, producing electricity according to Maxwell's equations. Theoretically the wires could be held still and the mag…nets could be moved (the equations work out the same either way), and in practice this is generally done for simplicity in very large AC generators which use electromagnets to generate the magnetic field (the field current is much less than the armature current, so having a stationary armature and moving magnets turns out to be easier). The magnets in a simple generator are usually permanent magnets, but using electromagnetic "field coils" instead allows a higher flux density and is generally done in large commercial generators.
Magnets are just rocks that come from the Earth. The Earth has grvaity, and when the magnets come up frm the ground they keep there gravity with them and thts how it wrks.
Any time a magnet's flux lines cut past a conductor (wire), a small pulse of electricity is generated. A generator is the same as a motor, except, it's rotor core is rotated b…y external means (wind, waterfall from a dam, steam and so on). As the rotor rotates, the magnetic field lines cut the conductors creating a pulse of electricity. The faster the rotor is rotated, the more power you will generate. You can experiment by using a small toy motor, connect the wires to a small low voltage light bulb, then rotate the rotor; the light bulb will light up.
Electricity produced by magnetism is called induced voltage. It is by induction, the passage of a magnetic field across a conductor, that a voltage will be induced ("caused" o…r "made to happen") in that conductor.
If a conductor - such as a wire - moves through a magnetic field, a voltage is produced in the conductor. This may cause a current (if the wire is connected to an external cir…cuit). This effect is used in generators to generate electricity.
The simple answer is by induction. Induction is the "sweeping" of a magnetic field across a conductor and the generation of electromotive force (EMF) or voltage in this action…. By taking a rotor with many turns of wire on it and rotating it inside a stator, which has a permanent magnetic field (either from permanent magnets or, more likely, an electromagnet), we generate electricity. It's done all the time.
it can easily be done by using the magnet attraction and creating rotation , for more inf go to www.magpower.us
If you wrap a coil of wire around a bar of iron and pass a current, an electromagnet will result. This principle is used in generators where the casing is magnetised and the r…otor rotates in the magnetic field inside the casing(the armature), inducing a current in the rotor winding.
Yes. That's how generators work.
It creates electricity by connecting to something(conductor).
The first law of thermodynamics is that matter/energy cannot be "created" or destroyed. We can convert energy from one form to another. For instance, in a car, we …convert chemical energy (actually the binding energy of electrons) to heat, which in turn is converted to kinetic energy (motion).Your question has a similar answer. When you rotate a magnet, you are using kinetic energy to move it. This kinetic energy can be converted to electrical energy by taking advantage of the properties of electromagnetism. Since you can't "create" energy, the amount of electrical energy produced will always be the same or less than the amount of energy you put in. Actually, it can't be exactly the same, because there is always at least some energy converted to heat by friction. This wasted energy results in an energy conversion "efficiency" which is less than 100%. The classic application of your example is the electric generator.One of the most useful and beautifully symmetric principles in physics is the connection between electricity and magnetism. This connection can be described like this. Electrons feel the force exerted by a magnetic field. This is because electrons behave like tiny magnets, with North and South poles. So a magnetic field will have an effect on electrons in that field. If the field moves, the electrons in it will try to move. Conversely, if we have electrons in motion (electric current in a wire, for instance), these moving charges exert a magnetic force (because of their magnet-like property). So, if you glue a magnet onto an axle, and turn the axle, you create a spinning magnetic field. Place a length of wire around the spinning magnet, and an electric current (moving electrons) will occur in the wire. This is called induction. If you wrap the wire multiple times around, you increase the amount of current induced. You can verify this if you have a very sensitive ammeter to measure the current with. Now we can also take a length of wire and coil it up, then run electric current through it. Because of the magnetic properties of electrons, this coil becomes an electromagnet. And we could go even further. Take that electromagnet, and spin it (we'll use something called 'slip rings' to keep our wires from twisting up), and you have another spinning magnetic field from which you can induce electricity.
Yes, General Electric helped to create Wipro in that it helped them expand their range of products and services. In 1989. General Electric went into a joint venture with W…ipro in order to manufacture, sell and service imaging and diagnostic products.
When an electric current flows, electrons are being transferred from one atom to another. This electron transfer creates a polarity in the atom, which translates to a magn…etic field.
Magnets generate electricity by moving the magnet along a conductor, such as a wire. This is called induction. When magnetic lines of force sweep across a conductor, the magne…tic field induces a voltage in the conductor. Voltage is "electrical pressure" and if a supporting circuit is set up connected to that conductor, current will flow.
A flow of electric current creates a surrounding swath of magnetic flux. This flux will mingle with and surround the current flow. If the current is bent by say winding a wire… in the form of a coil, the flux will shape itself around the coil. The strength of the flux will vary with the current. Reversing the current reverses the flux direction.
