What is a leakage flux and how this term is applied on the equivalent circuit of the iron core transformer? (b) Explain fringing and its effect on the magnetic flux and on the magnetic flux density. (c) What is a difference between a static and dynamic hysteresis loop? (d) Explain in detail iron losses.

The figure below shows an iron core with all measurements given in cm. The thickness of the core (into the plane) is 1 cm. Assume that the magnetic flux density, B, is evenly distributed across all cross sections in the core, so that ϕ = BA. The core has a relative permeability of 5000. The number of windings, N, is 100, and the current, I, is 1mA. a) Draw the magnetic equivalent circuit of the system in Figure 2. b) Reluctance of one part of the circuit, Rmi, is defined as Rmi = li / (μi Ai) Assume straight flux lines in the air gap (no fringing). Find the reluctances in this circuit. c) Find the flux through the formula below. ϕm = NI / ΣRmi d) Assume an infinite relative permeability in the iron core. Recalculate the flux. How large error does this induce (in %)?
