explain 4 maxwell equations???
Answer / vijay singh bisht
JAMES CLERK MAXWELL a pioneer who unified two big fields
called electricity and magnetism and a new branch called
electromagnetism emerged. maxwell work is a combination of
4 equations. these r
1- gauss law in electrostatics. statement- surface integral
of electric field in vaccum is equal to one upon ebsollon
times the charge enclosed in side the surface.
in simple terms this eqn explanes that charges(at rest or
in motion) have their own electric field.
2- gauss law in magnetism. statement- surface integral of
magnetic field in vaccum is 0. ie the net flux is 0 since
incimming flux = outgoing flux.
3-faradays law of emi(electromagnetic induction). it gives
the working principle of all generators and motors.
statment- line integral of electric field is equal to the
negative of the rate of change of flux.
in simple words when a conductor is moved in magnetic field
(or magnetic field is moved wrt conductor) an emf(voltage)
is induced in the conductor. the emf produced is
proportional to the rate of change of flux
4-ampere circuital law. statment- line integral of magnetic
field is equal to mue 0(permeability of vaccum) times the
current flowing thru the conductor.
in simple words it means a current carrying conductor
produces a rotational magnetic field.
fourth eqn was corrected by maxwell.ie amperes eqn with
maxwell correction.

i completed my b.tech recently with full credits... i have confused in calculating my backlogs...actually i failed in 6 subjects(1 in 2-1,4 in 3-2,1 in 4-1) but i cleared them in one attempt in their respective supplymentry.... then how many backlogs i had now... tell me cleraly.....
