In a lossless, magnetically linear system consisting of a stationery core and a movable bar as shown. The bar is confined to move in the vertical direction x (positive reference is downward). Assume that the stationary core and the movable bar have infinite permeability and that the gaps 1 and g are very small. stationary core movable bar W X. W μ1-00 i(t)T μ-400 N turns λ(t), v(1) W W W SEP x(1) Depth d into the page a) Find the magnetic field intensity H in the three air gaps as a function of i and b) Derive the electric terminal relation between the flux linkage and the current. What is the self-inductance of this magnetic circuit? c) What is the terminal voltage? d) What is the coenergy stored in the system? e) What is the magnetic force acting on the movable bar? Show that this force is always attractive regardless of i or x. In a lossless, magnetically linear system consisting of a stationery core and a movable bar as shown.
