V (Voltage) or I (income) or ... can be convert to magnetic field?
any body here?
You need to ask a coherent question.
i want know that voltage (in electromotors) creat magnetic field or convert to magnetic field?
Voltage does not create or "convert" a magnetic field. A current, however, does create a magnetic field.
So A creat the magnetic field and any things cant convert to magnetic field?!?
So the electro motors spend energy with resistance?
I would recommend that you spend some time reading at www.wikipedia.org in order to start to understand the concepts you are asking about. Try going to that website and searching on the keywords that you are asking us about, like
Separate names with a comma.
