because eddy current is produced by the heat produced in winding
Yes, a transformer has eddy currents.
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.
to reduce the eddy current loss in the machine

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.
air friction ,fluid friction, eddy current
Eddy current damping is not practical in moving iron instruments because these instruments rely on a magnetic field produced by a coil to move a ferromagnetic element. The rapid motion of this element can create eddy currents in nearby conductive materials, but the inherent design and operation of moving iron mechanisms do not allow for effective energy dissipation through these currents. Additionally, the presence of eddy currents can interfere with the magnetic field and the accuracy of the instrument, leading to potential measurement errors. Thus, other damping methods, such as air damping, are preferred.
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.

Yes, a transformer has eddy currents.
To convert a WPA eddy current galvanometer into a ballistic galvanometer, you need to adjust the instrument's damping and sensitivity settings. This typically involves minimizing the damping by removing or altering the damping mechanism, such as the fluid or spring system, to allow for quicker response to transient currents. Additionally, you may need to change the coil's configuration and increase its inductance for better performance in measuring the brief currents associated with ballistic measurements. Finally, ensure that the scale and calibration are appropriate for the expected current pulses.
