The core of figure 2 is made of cast steel. Calculate the curent I that needed to establish a flux of Og = 6 x 103 Wb at the air gap if fringing field is neglected Cast steel A=2x 10-2 m² 4= bc= 0.25 × 10-3m N=200 lab = led = 0.25 m a = 0.2 m ldea = 0.35 m

How many lines of magnetic flux must be cut in 1 s to induce a voltage in a coil?

A flux of 0.0016 Wb flows in a silicon sheet steel coil/core. The arrangement appears as shown below with the following dimensions: Ac = 0.0025 m? Core/gap area: Flux path length: le = 0.350 m lg = 0.0015 m N = 500 Air gap length: Number of turns: %3D A. What is the current, I, through the winding? B. What is the energy stored in the inductance? C. Assume that the current is given by i =9.75 sin (3147) A. What is the RMS voltage that would appear across the winding? D. Assume that the gap is removed from the arrangement with the flux path remaining at 0.350 m. For a flux of 0.0016 Wb, what is the inductance of the arrangement? E. What is the energy stored in the inductance with the gap removed?
