How demagnetize an electric motor?
A transformer winding only produces a magnetic field when current flows through it. Switch the current off, and the magnetic field disappears. You do not need to 'demagnetise' a transformer winding.
Does electrical power lines pass through step down transformer or step up transformer before entering you home?
A step-down transformer supplies electricity to your home. The values of voltage involved depend on the electrical standards in your country. For example, in the UK, the primary nominal voltage is typically 11 kV, and the secondary nominal voltage is 400/230 V (three phase) or 230 V (single phase). Incidentally, the power lines do not 'pass through' a transformer. They terminate at the transformer's terminals. Energy is transferred from the primary to the secondary through mutual induction. The primary and secondary windings are electrically isolated from each other.
Which is the maximum efficiency machine between Alternator and Transformer?
the efficiency of transformer is more than alternator, because 1- the alternator have friction and windage loss but in transformer this not occure. 2- in the alternator the flux leak is more than the transformer, because in case of alternator the flux move through the air which is dimagnet and in transformer flux move through silicon steel. 3- in the other hand alternator have dc compound generator for exciation (depend on other electric course 220volt) but in t/f is not need.
What is through fault?
A fault occurs by 2 plates sliding along each other and then breaking.
Does the ac generator produce the 11kv or we get the 11kv via step up transformer?
I've seen AC generators that have output voltages from 120v to near 30kV. Likely you get your electricity from a large generator, that is connected to a step up transformer (few kV - 30kV stepped up to transmission voltage levels of 100kV - 750kV), which transmits the power through the bulk electric system, then down through step down transformers, through subT and distribution networks to your home.
What is step up tranformer?
A step-up transformer is a transformer that increases voltage that is transferred through power lines.
Why does the core of a transformer heat up?
The resistance to the electric flow through the wire coil causes heat

How is electric energy transferred?
Usually through wires. Over long distances, it is usually transferred in the form of AC (alternating current), since in that type of electricyt it is easy to increase or decrease the voltage through transformers.
What does the lines between primary and secondary coils of transformer signify?
The voltage in a transformer is transferred from primary coil to secondary coil through electromagnetic induction. There is no physical connectivity between these two. instead they are linked by an alternating magnetic field created in the soft-iron core of the transformer.The two lines in the middle of the circuit symbol represent the core of the transformer.
The heat from an electric space heater is transferred to you by?
all objects emit electromagnetic radiation through empty space, as well as matter. So feel the heat from the electric heater due to radiation.
