For the circuit shown in Figure:a. Determine the reluctance values and show themagnetic circuit, assuming that μ = 3,000μ0.b. Determine the inductance of the device.c. The inductance of the device can be modified bycutting an air gap in the magnetic structure. If a gapof 0.1 mm is cut in the arm of length l3, what is thenew value of inductance?d. As the gap is increased in size (length), what is thelimiting value of inductance? Neglect leakage fluxand fringing effects.

Boundary Conditions Two planar slabs of equal thickness but with different dielectric constants are shown inFigure. Eo in air makes an angle of 30° with the z-axis. Calculate the angle that E makes with the z-axis in each of the two dielectric layers.
10 Given a common magnetic core whose length is 100 cm, its cross-sectional area is 25 cm square. The relative permeability of the core material is 5000. Two coils are tightly wound on the core. N1 =1000 turns and N2 = 500 turns. The self-inductance of coil N1 will be: [ 7.85 m H 15.7 m H 3.927 m H 5.17 mH

A cylindrical solenoid 49 cm long with a radius of 7 mm has 325 tightly-wound turns of wire uniformly distributed along its length (see the figure). Around the middle of the solenoid is a two-turn rectangular loop 3 cm by 2 cm made of resistive wire having a resistance of 135 ohms. One microsecond after connecting the loose wire to the battery to form a series circuit with the battery and a 20 resistor, what is the magnitude of the current in the rectangular loop and its direction (clockwise or counter-clockwise in the diagram)? (The battery has an emf of 9 V.)
Write this out clearly
4) We usually think of wires as perfect (R=0) conductors, which is not quite accurate. Real wires have resistance albeit small - usually less than an ohm. With this in mind: a. Consider a uniform cylindrical copper wire that has diameter of 1 mm and is 10 m long. What is the resistance of this wire? The resistivity of copper is 1.72 x 10-8 9-m. b. This wire is cut in half, and the two strands are used to connect an electric heater to an outlet supplying 1500 W at 120 V. Draw a simple circuit diagram, including the voltage source, resistances of the connector wires, and the calculated resistance for the heater. C. How much of the total 1500 W is absorbed by the connector wires, not by the electric heater? d. If the specific heat and density of copper are 385 J/kg°C and 8940 kg/m³ respectively, how much will the connector wires heat up after 1 minute of use? (Assume all energy absorbed by the connector wires is converted to heat and remains in the copper wire.) Remember that E cmAT,…

A solenoid is to have an inductance of 0.285 mH, a cross-sectional area of 6.00x10-4 m2, and a length of 36.0cm. How many turns per unit length should it have? (Ans. 1.02x103 turns/m) If the self-induced emf is -12.5 mV at a given time, at what rate is the current changing at that instant. (Ans. 43.9 A/s)
