What is the difference of eddy and vortex?

The difference is that eddy make wind, water change direction and vortex its just awhirlwind or whirlpool.


Why induced emf in transformers lag excitation current?

All magnetic materials require some energy before they will operate. You can think of it as the price of admission. In an electrical transformer, the excite current is actually a composite of the energy which is lost due to eddy currents in the magnetic material as well as hysteresis losses of the material. Excite current is both frequency and voltage dependent. Instead of saying, "before my husband will do anything I have to bake him a cake", you could say"before my transformer runs at 115Vinput, I have to supply x milliAmps of excite current just to get the core going." A special class of transformers known as CT's or Current Transformer's works in much the same way, except their voltage is reflected off the load instead of coming directly in through the primary. This energy is dissipated as heat. In power transformers, the concern is energy lost with no load connected on the output. In current transformers, the concern is the varying loss of accuracy due to the highly non-linear nature of excite current, especially at low excite levels.

How did artist create fresco?

Fresco is created when earth tones are applied directly to wet plaster. The creation of paintings such as those within the Sistine Chapel were created in just such a manner.

Core loss of an induction motor?

Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.


How does diode acts as a switch?

When the diode is reversed biased (positive charge applied to the N side and the negative charge applied to the P side) no current can flow just like when a switch is off. When the diode is forward biased (positive charge applied to the P side and the negative charge applied to the N side) no current can flow just like when a switch is on. Current can only flow in one direction.


How do you use the word eddy in a sentence?

The boat got into a violent eddy in the water, making it go around and around until everyone was feeling sick and dizzy.ExplanationIn water flow, an eddy is a current that flows opposite to the major flow, also known as a whirlpool.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.Another exampleEddy is my best friend. (That example is just for a person called Eddy, not for the word "eddy", which is another word for a whirlpool!)

Why does a magnet only stick to things made of iron or steel?

It doesn't. It's just that those are the two ferromagnetic materials you're most likely to run into. A magnet will stick to nickel or cobalt just fine (note that US "nickels" are mostly copper, which isn't ferromagnetic).


What can be done to minimize eddy current losses?

Changing magnetic field causes to produce eddy currents that are confind within the core of transformer. these are like circulating whirls inside the core. these can be eliminated by making the core of thin layers. "Eddy current losses occur whenever the core material is electrically conductive. Most ferromagnetic materials contain iron: a metal that has fairly low resistivity (roughly 10-7 Ω m). The problem is intuitively obvious if you consider that the magnetic field is contained within a 'circuit' or loop formed by the periphery of the core in the same way as it is contained within a turn on the windings. Around that periphery a current will be induced in the same way as it is in an ordinary turn which is shorted at its ends"


Why you put distilled water in a battery?

Any foreign objects or minerals in tap water will produce an "Eddy Current" which lowers your batteries efficiency by lowering its current capabilities. Without getting too technical (hole flow theory etc..) Lets say the current inside your battery goes from Pos. + to Neg. - If one anode is pos. then it will see debris in the water as something less pos., or actually a neg. So it will send current to the debris instead of the neg. anode. This is called "Eddy Current". Just like a stream with a flat bottom flows faster than one with a lot of rocks which produce eddyies.

Is a paper clip paramagnetic?

No, just very weakly ferromagnetic. Unless your paperclip is made out of NH4[Fe(SO4)2]·12H2O.
