Top Section: Title: Electrodynamics Statement: E and B can be time-dependent. Explanation: These E and B fields are produced by accelerated charges (v ≠ constant). Diagram: A sketch illustrating the relationship between electric (E) and magnetic (B) fields. Bottom Section: Label: Ques.9. Page-59 Circuit Diagram: A diagram of a circuit containing a resistor (R), an integrator (op-amp with a capacitor), and a voltage source (Vin). Equations: Vout = 1/RE * ∫Vindt Vin = Ɛ = -dΦm/dt Header: Ch.3, Page-57 Initial Condition: At t=0, magnetic flux = 0 Explanation: We need to use the flux method because the angle between the magnetic field and the area vector is changing. Magnetic Flux: Φm = ∫B⋅dS = BAR²sin(ωt) Initial Conditions: If the loop initially contains no flux, use the sin function. If the loop initially contains maximum flux, use the cos function. Induced EMF: Ɛ = -dΦm/dt Equation for Induced EMF: Ɛ = -BAR²ωcos(ωt) Graph: A graph showing the variation of induced EMF (Ɛ) with time (ωt). Equations: Ɛpq = -ωBL²/8 Ɛpq = ωBL²/2 Graph: A graph showing the variation of Ɛpq with time (ωt). Explanation: For a rotating rectangular loop in a magnetic field, the induced EMF (Ɛpq) is given by the above equations. The sign of Ɛpq depends on the direction of the magnetic field and the loop's motion. In certain conditions, Ɛpq can be zero.
