How does a volcanic eruption effect photosynthesis?
A volcanic eruption puts ash into the air, which cuts off sunlight to the plant. Light is needed for photosynthesis to happen, so photosynthesis wouldn't happen if a volcano erupted near the plant.
What rotates to create electricity?
a rotor which is powered with a dc voltage using a commutator turns within a stator winding system, and the created magnetic field cuts through the stator windings and induces a voltage into the electrical winding circuits.
What changes the flow of electrons in an alternating current?
first of all the voltage doesn't change what changes is the current direction the way they do it is by using magnet . electrons tend to escape from the magnetic field . you can find on you tube how a motor works for better idea.
What are the most common cuts for amethyst?
common cuts on amethyst
Which river cuts tropic of cancer twice?
The River Mahi cuts through the Tropic of Cancer twice.
What makes the armature in the electric motor rotate?
from Faraday's law of electromagnetic induction : when a current carrying conductor cuts the magnetic field an E.M.F (electro motive force) is produced and it sets up in such a direction so as to oppose the cause of it. the stator winding of a motor which produces the R.M.F (rotating magnetic field) serves as the magnetic field and the armature winding is the current carrying conductor which cuts the magnetic field , thus an EMF is induced in the armature which again produces a force to oppose the emf produced in the armature winding.
What is armature current according to generator terms?
Generator is a machine which converts mechanical energy into electrical energy.For conversion of mechanical energy in to electrical energy, it uses electromagnetic induction principle.For electromagnetic induction to happen, three things are required.These are:Magnetic fieldConductorMotionSo, when the conductor starts rotating through the magnetic field or the magnetic field cuts the conductor, emf( electromotive force) or voltage is induced in the conductor.So, the conductor in which the voltage is induced in it is known as armature
What 3 factors that affect the output of a generator?
1:The strenght of the main magnetic Field. Determined by the strenght of the field magnets in a permanent magnet machine, or by the number of turns of wire on the field coils and the current through the coils in a wound field machine.2: The number of armature conductors connected in series, which cut the main magnetic field. Determined by the number of turns on armature coils and weather the armature is lap or wave wound, which determines the number of armature conductors connected in series.3: The speed at which the armature conductors cut the main magnetic field. The faster the armature cuts the magnetic Field, the higher will be the value of the voltage generated in the machine
How could the electromagnet and the regular magnet generate electricity?
Before going to the answer first I'd like to tell that Magnet alone cannot produce electricity. We need an armature. Armature contains poles. Consider that armature is placed in between the magnetic poles(North and south poles) and let it face any direction. Due the magnetic field the armature tend to move towards anyone pole in order to make its direction coherent with the magnetic field direction. It results that armature is aligned with the magnetic field direction(lets say facing North). Then the other pole(South pole) tend to attract the armature to align in its direction say(facing South). This results in rotation of the armature in the magnetic field. due to this rotation of armature cuts the flux there emf is produced. This emf cause the current in that construction. This is how the electricity is produced using any magnet called Electromagnet or Permanent magnet.
Operation of DC generator?
1) PRINCIPLE:Whenever a conductor cuts magnetic flux, dynamically induced emf is produced in it. ( Faraday's Laws of Electromagnetic Induction ). This emf causes a current to flow if the conductor circuit is closed.2 ) OPERATION:Field winding produces magnetic field in D.C. generator. Armature is coupled to the prime mover. Prime mover produces torque so the armature rotates. The armature cuts the magnetic field so the emf is induced in the armature. When load is connected to the armature, electric current flows from the armature conductors, through load and back to the armature conductors. Now, as current flows through the armature and it is in the magnetic field, torque is produced due to it. (This torque is called back torque). If the load on the generator is increased, the back torque increases so the torque of the prime mover also increases and the input power to the prime mover increases. In this way, the generator converts mechanical energy into electrical energy.It should be observed that the emf induced in D.C. generator, is A.C. ( so the emf induced in the armature is alternating in nature. ). Then with the help of commutator, it is converted into D.C. Rings and brushes are used to take the emf outside.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
When lines of force are cut by a conductor you have magnetic?
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
How do you explain the magnetic effect of an alternator?
How alternators workAn alternator is an a.c. motor in reverse; the coils of the armature (the part that rotates) cuts through the magnetic field of the stator (the part that is stationary, which is what "stator" means). A current is produced whenever a wire cuts through a magnetic field; the amount of current depends upon the strength of the field and the speed of the wire. This current is coupled out of the armature by two copper rings and a pair of brushes. For automobiles, the a.c. (alternating) current is converted to d.c. (direct current) by rectifiers (also called diodes). ERROR: A voltage is applied to the rotor winding by way of the slip rings. This creates an electro magnet who's field cuts across the stator windings. The stator winding voltage is an alternating current that is retified and regulated and is outputed out at the terminal on the back of the alternator. This is exactly the reverse of the above. If the above were true the brushes would smoke when a high current passed through them
Working principle of generator?
An electric generator is a device which converts mechanical energy to electric energy. An electric generator basically works on two principles, they are:- 1. Electro magnetic induction: This was first discovered by Michael Faraday this law states that when a electric conductor moved through a magnetic field cutting the electro magnetic waves, a electric charge is produced in the conductor. 2. Flemming's right hand rule: Place your thumb finger, index finger, and your middle finger in such a way that all the three are mutually perpendicular to each other. Here if your thumb points the thrust or force and index finger points the electro magnetic field then your middle finger points the direction of induced current. An electric generator consists of a electromagnet or a huge horse shoe magnet in which an armature is enclosed. The armature is made of copper coils. Now when the armature is rotated, it cuts the electro magnetic waves generated by the magnet and hence as a result of electro magnetic induction electricity is generated in the armature and the direction of the induced current can be found out using the Flemming's Right Hand Rule. And how the electric current produced later is stored and carried out differentiates between AC generator and DC generator
When a conductor cuts magnetic flux an emf is induced in the conductor. This is known as?
faraday law
What is the process called in which a conductor cuts across a magnetic field and produces a voltage?
We call it induction when we pass a conductor through a magnetic field to produce voltage.
What happens when a magnet is moved towards a coil?
You will generate electricity. As the wire cuts through the magnetic field.As the magnet is moved, there will be an induced electro-motive force (EMF) which can cause a current in the coil. Once the magnet stops moving, the current will go to zero.
