How does a generator use electromagnetic induction?
There is a motor in a generator which carries out this electromagnetic induction,as we switch on the generator the magnetic field lines between that motor get cuts off by the rotating coil which cause change in flux and change in flux cause induced emf,cue to emf at different points of coil cause current to get flow and then generator will get on.
What electronic device is used for induction?
The inductor is basically used for induction in electronics domain. such in the transformer inductor cause the electromagnetic induction which cause the flux to link with secondary winding and generate the voltage on secondary winding.inductors are also used in tunned circuits.
How is wind made into electicity?
Wind can be made to drive windmills which can cause turbines to rotate. The turbines have electromagnets which move through coils. By electromagnetic induction this generates an electric current.
Why do electrons cause a light paddle wheel to rotate?
Once the electrons hit a spoke of the wheel, The spoke gets heated on one side. This causes the gas next to the spoke to expand. As the gas expands, it pushes the side of the spoke that was heated. This results in the rotation of the wheel.
Do dynamic microphones require a power source?
No, dynamic microphones do not require a power source to function. They generate electrical signals through electromagnetic induction when sound waves cause a diaphragm to move within a magnetic field.
How much pollution does a electromagnetic wave cause?
Electromagnetic waves only cause sound pollution because they are sound waves.
4 effects that can happen when electromagnetic radiation is absorbed?
When electromagnetic radiation is absorbed, several effects can occur: it can increase the energy of the absorbing material, leading to temperature rises (thermal effects); it may cause electrons to be excited to higher energy levels, resulting in fluorescence or phosphorescence; absorption can also lead to chemical reactions, as seen in photosynthesis; finally, it may cause ionization, where atoms are stripped of electrons, potentially leading to damage in biological tissues.
In an electric motor periodically changing the direction of current in the electromagnetic can cause the axle to spin because?
In an electric motor, periodically changing the direction of current in the electromagnet causes the magnetic field to alternate. This changing magnetic field interacts with the permanent magnets on the rotor, creating a rotational force that causes the axle to spin. This process is known as electromagnetic induction.
What role does induction play when lightning stikes earth?
Electrons move from areas of negative charge to areas of positive charge and produce an intense spark. Some lighting reaches Earth because negative charges at the bottom of storm clouds may cause the surface of Earth to become positively charged by induction.
What occurs when an electric current is made by a changing magnetic field?
We might call it induction, magnetic induction, or electromagnetic induction, depending on what kind of setup we were inspecting. It is the phenomenon of induction that allows a moving magnetic field to cause (induce) current flow in a conductor. A link can be found below for more information.
What is the Cause of the movement of electrons?
The movement of electrons is caused by the presence of an electric field or voltage. Electrons are negatively charged particles that are attracted to positively charged particles; so when a potential difference is applied, electrons move towards the positive terminal, creating an electric current.
