why the magnetic field is difficult to empirically defined

Question

anonymous · Answer

Well.. 
thats because we have an electric charge.. a source for electric field.. 
but we don't have a magnetic charge.. moving electric charge produces magnetic field.. so its little bit difficult to define it empirically !

anonymous · Answer

can you give me example?

anonymous · Answer

or simulation?

anonymous · Answer

Example of what?! .. tell me specifically what you wanna know :)

anonymous · Answer

its confused for me, that electryc field can defined empirically with forece electryc and q.
then we know  that E=F/Q

anonymous · Answer

yes.. because the force experienced by an electric charge in an E field.. depends ONLY on the charge itself

hence we can define the E field as F/Q 


however the force experienced by a charge in a magnetic field depends NOT only Q, but also on Velocity V, and also the angle of the velocity with B.. so while definining .. we need to include all those as well

Electric force is completely independent of Velocity or its angle.. so that doesn't come in the definition.. get it?!

hmmm,yeah...
another  case,how to explain the kinetic energy generated by the electric motor/

anonymous · Answer

That is a very good question.. but i wanna know if you understand that question

so tell me. what is the problem ?!

anonymous · Answer

how step by step  from this process/

anonymous · Answer

no no.. first tell me.. what is the question..?? why do we need an explanation .. isn't it enough if we say, electrical energy is converted into kinetic energy?

anonymous · Answer

yes,its  to short...
what happen when the electrical energy converting to kinetic energy?

anonymous · Answer

that is not the purpose of the question.. 

first answer me this.. 
if there is a charge that is shot perpendicular to a magnetic field.. then due to magnetic force, can you tell me what path the charge takes?

anonymous · Answer

current in copper?

anonymous · Answer

huh?! .. no.. if i had a free charge.. just one charge.. say a proton.. if a proton is shot perpendicular to the magnetic field.. what path it would take?

anonymous · Answer

move ?

anonymous · Answer

what? o.O  don't you understand my question?! the PATH.. what will be the PATHHHH of the proton?!?!?

anonymous · Answer

yes , i dont understand what will be the pathh of the proton

anonymous · Answer

then you need to work on your magnetic forces. a little bit more, before trying to answer that question :P

anonymous · Answer

this  is clue "work"

anonymous · Answer

yea.. well.. unless you can answer my question, you can't answer your question :P

anonymous · Answer

greats my friends :P
