MAXWELL’S EQUATION FOR
TIME VARYING FIELD
FARADY’S LAW OF INDUCTION
• A CONDUCTING COIL PRODUCES A CONSTANT
    MAGNETIC FIELD WHICH IN TURN PRODUCES A
    CONSTANT FLUX THROUGH THE LOOP IF THE LOOP
    DOSE NOT MOVE.
•   A CURRENT FLOW IN THE LOOP IF IT IS TURNED
    AROUND SUDDENLY OR MORE CLOSER TO THE
    COIL,DUE TO FLOW OF CURRENT A VOLTAGE INDUCED
    IS CALLED ELECTROMOTIVE FORCE(EMF).
•   Vemf = -N dΦ/dt
•   ▼×E= - ∂B/ ∂t

2.TRANSFORMER
• A TRANSFORMER CONSISTS OF TWO COIL WOUND
    AROUND A COMMON MAGNETIC CORE.
•   THE COIL OF PRIMARY CIRCUIT HAS N1 TURNS AND
    IS CONNECTED TO AN A.C VOLTAGE SOURCE V1(t)
•   THE COIL OF THE SECONDARY CIRCUIT HAS N2
    TURNS AND IS CONNECTED TO A LOAD OF
    RESISTOR RL.
•   ON THE PRIMARY SIDE OF TRANSFORMER V1
    GENERATES A CURRENT I1WHICH ESTABLISH A FLUX
    IN THE CORE.
•   V1 = -N1 dF/dt.
•   ON THE SECONDARY , THE FLUX CREATES A
    VOLTAGE V2.
•   V2 = -N2 dF/dt.

• THE COMBINING OF THESE EQUATION GIVES.
• V1\V2 = N1\N2 = I2\I1.
3.MOVING CONDUCTOR IN STATIC MAGNETIC
FIELD.
• The force acting on a charge q of the wire is
  Fm=q(uxB)
• The quantity (uxB) is called the motional
  electric field Em.
• The electrons of the wire will then move
  in the opposite direction of Em, and this
  induces a voltage difference between
  ends 1 and 2.
           CONCLUSION
AN ELECTRIC FIELD IS PRODUCED BY A TIME
VARYING MAGNETIC FIELD AND VICE VERSA.
MAXWELL’S EQUATIONS FIND MANY
APPLICATIONS OTHER THAN DISCUSSED HERE
SUCH AS IN ANTENNA DESIGN ,WAVEGUIDE
DESIGN,DETERMINING BOUNDARY
CONDITIONS,PLANE WAVE PROPAGATION ETC.
