You can be his favourite with a penis... if Lougan agrees... but I would know nothing of that

I reserve the right to say "Don't be a prick," yet be one myself.

but uh just wondering.... if two people would have yelled TOM instead of just one.... would you have turned into a GPS unit?

Magnetic fields don't really exist...... they are just a description of half of an electromagnetic field.
If I were you, I would refuse to pay your tuition bill. You are getting jipped.
Magnetic fields allow electromagnets, generators, transformers, alternators, and even microwaves to function.
If you think magnetic fields do not exist, try finding your way out of a forrest without a compass.
To suggest magnetic fields do not exist is like saying wind does not exist. I can only describe the efftects of the wind like I can only describe the effects of magnetism. Therefore wind does not exist???
Magnetism is only a theory. There are NO magnetic laws. Regardless, to suggest the universe exists without magnetic fields is quite frankly, stupid.
Please get to your point...

Here is a quote from wikipedia explaining this development in the history of physics:
In the past, electrically charged objects were thought to produce two types of field associated with their charge property. An electric field is produced when the charge is stationary with respect to an observer measuring the properties of the charge and a magnetic field (as well as an electric field) is produced when the charge moves (creating an electric current) with respect to this observer. Over time, it was realized that the electric and magnetic fields are better thought of as two parts of a greater whole - the electromagnetic field.
Just curious...... Who is stupid now? ^.~

Induction is the principle by which transformers function. A coil (two or three in one xfrmer) of copper is placed in series or parallel to another coil of copper which is in turn placed in close proximity to another coil of wire. The electromagnetic field induces a voltage into the secondary coil directly proportional to the ratio of turns between the two.
Motors, work through a similar principle, except they work with coils and relative motion. The coils rotate, or sometimes the stator rotates, to create relative motion between coils of wire and permanent magnets. This also creates a magnetic field.
Try wrapping a fine, bare wire around the long shaft of a screwdriver. leave enough wire from both ends to touch to a 9 volt battery. while holding the wire on the battery, pick up a paper clip with the shaft of the screwdriver. You have created a DC magnetic field. If the wire were not in a coil, the magnetic field would be nearly immeasurable.

Or is this just some random middle school factoid which has nothing to do with why you called me stupid?
