Yes, Light behaves as a wave and particle and it known as De-Broglie Wavelength ---> lamda = h/m*v.
Light behaves as a wave --->diffraction, reflection and refraction.
Light behaves as a particle-----> Compton effect and Photoelectric effect.

Light is a wave and a particle why?

Hysteresis loss is created by magnetic core due to alternating flux linkage and the second loss is eddy current loss or current loss. When flux is created electron tends to flow current in the core tends to cause current leakage as heat.

There is no machine in world that can be 100%used it energy to do work. So every machine losses the energy during working. How is expansion of transforming machine ti it?

In alternating current a power dissipation due to heating effect p=i2R so heat is produce and eddy current produce in transformer also and they absorbed by circulating oil so heat produce due to both phenomenon.

Armature means = the part of motor in which current is induced by a magnetic field. The armature usually consist of series of coils and groups of insulated conductors surrounding a core of iron.

T/f heating effect depends on frequency and voltage.

Heating effect is also due to resistance of wire and it is equal to p=2ir where I is alternating current.
Hysteresis loss is due to the magnetisation and demagnetisation.
