Eddy current in transformer?
Yes, a transformer has eddy currents.
What are the advantages of moving coil instrument?
Advantages are:- high sensitivity, uniform scale, very effective and reliable eddy current danping well shelded from any stray magnetic field. Disadvantages are:- very expensive, only suitable for direct current and voltages.
Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
What is the equation for calculating eddy current losses?
F^2into Bm^2
What is AD current loss?
AD current loss could refer to a comic, called Eddy Current. It could also refer to AD loss, memory loss caused by Alzheimer's Disease.
How many types of damping torque in moving instruments?
air friction ,fluid friction, eddy current
What are the different methods of damping used in analog indicating instruments?
Damping torque can be provided by: (a) air friction damping (b) fluid friction damping (c) eddy current damping. In air friction damping, a light piston moves with a very small clearance in air chamber. The piston moves against pressure of air in air chamber. In fluid friction damping, light varies are attached to spindle of moving system. The movement of spindle is suppressed due to fluid friction, Eddy current damping is one of the most efficient method of damping. It is based on the principle that whenever a sheet of conducting but non magnetic material like copper or aluminum moves in magnetic field, eddy currents are induced.

How do you put eddy in a sentence?
I was swimming hard, salt water burning my eyes, when all of a sudden i got pushed violently by an eddy.
When was Eddy Current Suppression Ring created?
Eddy Current Suppression Ring was created in 2003.
Eddy current in transformer?
Yes, a transformer has eddy currents.
What is a metallic substance used in eddy current?
Alimunium is the best Element, that can be used for the production of eddy current.
What is a current of air?
An eddy.

Advantages are:- high sensitivity, uniform scale, very effective and reliable eddy current danping well shelded from any stray magnetic field. Disadvantages are:- very expensive, only suitable for direct current and voltages.
Why the name eddy for eddy current?
That's from an analogy from eddy currents in water. Quoting from the Wikipedia, article "Eddy (fluid dynamics": "In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid flows past an obstacle."
