A ferromagnetic core with a relative permeability of 1500 is shown in the Figure. The dimensions are shown in the diagram, and the depth of the core is 5cm. The air gaps on the left and right sides of the core are 0.050 and 0.070 cm, respectively. Because of the fringing effects, the effective area of the air gaps is 5 percent larger than their physical size. If there are 300 turns in the coil wrapped around the center leg of the core and if the current in the coil is 1.0 A, what are the flux values for the left, center, and right legs of the core? What is the magnetic field in each air gap? |7 cm 7 cm 7 cm to 30 cm 30 cm 7 cm 30 cm 0.07 cm 300 turns 0.05 cm 7 cm Core depth = 5 cm

A Suppose a copper conductor of length (UUm and cross-sectional area (A)m" and resistivity (6)N m, its resistance is [R = p(1/A)]. This copper conductor wounded around a ferromagnetic core, forming (N) turns. When this coil fed by a DC voltage (Va), its steady state current will be [lae = (Vac/R)]. But when this coil fed by an ms value of an AC voltage (Vms = Vdc), a steady state AC current of an rms value (lac) will pass through it. Explain the following questions: a) Why (lac < ldc) in this case, in spite of (Vms = Va)? What happens inside the electric circuit leads to reduce the current? b) What is the current waveform in this case? c) What is the voltage waveform across the coil? d) What is the type of the ammeter used in this circuit? e) Assume that the core length (le), cross sectional area (Ac), and its hysteresis loop data are known, what is its self inductance (L)? f) is the self inductance of this coil been constant? Or not? Why? g) If it is not constant, then what is it…
