Why eddy current damping is not used in moving iron instruments?
because eddy current is produced by the heat produced in winding
How is eddy current related to the thickness of the stampings of core?
A: Eddy currents are current losses if an iron bolt is used to hold the core lamination together that alone will cause losses. Usually a brass bolt is used to eliminate losses
How is a Bunsen burner used to identify a substance?
The role of Bunsen burner is to heat; some metallic ions have specific colors in the flame.
Why is soft iron used in electric bell?
Soft iron is used as the metallic substance which gets attracted to the electromagnet and a hammer is attached to the armature which strikes the gong when the armature is attracted.
What is exciting current in transformer?
Excitation current is the current necessary to "turn on" the transformer so it can be used. It's energy that is lost in the use of the transformer. Most of this loss I believe is associated with the hysterisis loop, although some will be lost as eddy currents.
What are the advantages of shell type transformers?
this type of transformer used special low loss steel to minimize eddy current losses and reduced leakage flux.
How are metallic salts used in fruits?
Any metallic salt is used for fruits !
What causes eddy current?
In magnetism:An eddy current is induced into a metal when magnetic lines of force move across it. A South pole causes circulating current in clockwise direction while a North pole causes current in counter-clockwise direction. These eddy currents thus buck the applied forces. Eddy currents are undesirable when induced into transformer cores causing power loss. Lamination of core material reduces current flow in the core. Current induced into the secondary winding of a transformer is a used to step-up or step-down voltages so that they can be of a correct size for end-use applications.When time-varying magnetic field is applied to electrical machines like transformers, a time-varying emf is induced in the transformer cores. A short circuit occurs at the molecular level in the core. Due to less resistance, a large current begins to flow in the core. This causes heating in the core. Actually the path of the current is circular resembling the circular waves in a pool of water (eddy). Hence these currents are called eddy currents.In fluids:In water flow, an eddy is a current that flows opposite the normal flow. If on a river, an eddy is a current that will flow upstream in a side channel filling it, even if the flow is in an opposite direction of the original flow. It is equivalent to a stream's water level rising because the river it feeds has more water in it than the stream, thus making the water flow upstream. It can also be an area that seems not to have a current at all.A:Just like there exists a magnetic path due to current (charge) flow in a conductor (direction given by right hand rule), the thing works other way as well...When there is a flux path crossing a current conducting material, there exists current paths around the flux line on the conductor plane centered to the point where flux line meets the plane. These currents are eddy currents.Commonly available in magnetic circuits. Laminations are done to minimize the ability to flow eddy currents.
Is there a river in Germany called the eddy?
no, but an eddy is related to all rivers and is a term used for a section in a river .
Why laminations are used for iron parts of a dc machine?
Laminations minimize eddy currents, or current flow across the iron parts. This is one method to minimze stray losses.
Who sings the song used in the AT and T commercials Take a walk down memory lane?
Eddy Current Suppression Ring is the name of the band. The song is titled "Memory Lane"
