why we want to get the determinant?

sorry. erm.. what does the determinant means or functions in matrices , math? thanks..

is "motional emf "the real explanation for the reason why emf is induced in faraday law?? thanks...

thanks for your help. can you tell me how is the Lorentz law done experimentally during his time? or give me a link telling this? thanks.. I have been searching this. but still couldn't get any result. thanks .

I don't really understand. why must we be introduced the flux? if a loop is at 30degree of let say 1T of B , can't we simply take the 1T for calculation for the induced emf? and I have a new problem. if a solenoid is set up, and I move near a magnet to the side of it instead of entering its...

can someone tell me , why must the magnetic flux be taken into account instead of magnetic field ?? thanks...

hmm.. thanks for ur replies... appreciate it much...

no other thing is under effect of B ? srry .i m not good in eng , hope u seniors can understd my q. thanks lot..

thanks much.. appreciate it...

for transformer , Zeq multiply with I .. let say the Zeq is ( 0.140 + j 0.532 ) , while I is ( 8.7 /_ -36.87 ' ) A ... -36.87 is degree.. how to multiply these two things up? please help me . i m in urgent.. thanks.. please...
