electrical trade theory
what is the function of the field coils of a DC motor? They provide a magnetic field that is opposite that of the rotating axle. Here is an interactive site that may help although this site has paermanent magnets for the field magnetism. (Broken Link Removed) THANK U DrBob222

Where does magnetism comes from? Magnetic forces arise from the movement of electrons (electric charge). In case you want it, here is more information on magnetism. http://en.wikipedia.org/wiki/Magnetism http://www.phy6.org/Education/Imagnet.html http://www.factmonster.com/ce6...

Which of the following statements for magnetism are true? (Give ALL correct answers) A) B does work on a charge only when the charge has a velocity component perpendicular to B. B) B acts only on charges at rest. C) B does work on a charge only when the charge has a velocity ...

Physic please check
I agree with your formula and numbers, but you are carrying too many significant figures, especially with the cosine. There should only be two significant figures. I have preferred to avoid Electricity and Magnetism questions because I don't remember the subject very well, and...

I have a few questions that I am not too sure of. why is it inadvisable to make a horseshoe magnet from a flexible material? -is it because it would have enough magnetism Do the poles of a horseshoe magnet attact each other? If you bend the magnet so that the poles get closer ...

i have to do this packet about magnetism, but we havent even learned anything about it yet. I have got some of the answers but i cant figure out the rest. What do you need to make an electromagnet? What is an advantage of using an electromagnet? Name 3 places where you would ...

Name and describe two ways in which magnetism is used in technology related to medicine? Im really not sure of the answer to this, but i do know that magnetism is the force of attraction or repulsion.

There is no such thing as a magnetic charge. Magnetism works in closed lines from N to S and back for example. You can have a + or a - electric charge sitting alone. Both types of electromagnetic phenomena have vector fields and the forces they exert are a function of where in...

Physics (please check)
a. voltage is directly proportional to loops. b. the domains are not perfect, some do not realign randomly when an imposing magnetic field is removed, thus, there is a residual net magnetism. c. Antennas can be designed for any length, given a proper feed transformer. You are ...

There are effects of magnetism and charged particles in the ionosphere, but that is well out of the atmosphere. http://en.wikipedia.org/wiki/Aurora_(astronomy)

im 11 years old do you know a science fair project i can do for magnetism. or a website. im in six grade

The first force you mentioned is usually called the "strong force". It takes place between "baryons" (such as protons and neutrons) whether they are in a nucleus or not. The second force is electrostatic, as you mentioned. It is part of the electromagnetic force. It is better ...

How is magnetism used to support the theory of seafloor spreading?
Monday, March 23, 2009 at 5:56pm by sara
The Earth's magnetic field will cause the newly formed seafloor to become magnetic. When the seafloor cools, the magnetism of the sefloor will become permanent. Then if the Earth's magnetic field changes direction (happens every few hundred thousand years), the seafloor's ...
