A bar magnet is any RECTANGULAR object that has a magnetic field.It can be made out of any ferromagnetic substance, but it is mainly made out of iron or steel. Most of the time, a bar magnet is a pernament magnet, meaning it does not need an electric current in order for it to retain its magnetism.

∙ 10y agoThis will depend almost entirely on the purpose for which the motor was designed and its power rating, not the fact that it is an electric motor.
Industrial electric motors used in factories can weigh tons and be larger than a minivan. Electric motors used in electronic equipment like computers and VCRs can be as small a pea. Electric motors can have almost any shape: cylinders, disks, boxes, etc.
Work has been done in laboratories on experimental electric motors so small they cannot be seen except with a microscope.

Witch part of an electic motor repels the poles of the permanent magnets?
The part of an electric motor that repels the poles of the permanent magnets is the fly wheel.
What is the electric field surrounding an electron It's defined as a force vector or warpage of space around the electron - what is this mysterious field made of what is it in a tangible sense?
The electron is surrounded by an electric field. The electric field can be represented by force vectors in models because the field will act on other fields. It will in concert with another field like it to push away, or act with another field opposite it to draw together. It's fairly simple like that. The "problem" with an electric or magnetic field is that is it invisible. Its effects can be seen, but the field itself, the force itself, is invisible. Like gravity. You can't "grab a handful" of gravity and look at it. And you can't do that with electric or magnetic fields, either. It's just there and it works. It works in accordance with the laws of electromagnetics.
How much power is developed by an electric motor that draws a current of 4 A when its operated at 240V?
P = I x V Power = volts x amps 240 x 4 = 560 watts. This is how much power will be consumed by the motor. The actual power produced at the shaft, will vary on type and efficiency of the motor.
