摘要： A multi-fed, multi-segmented magnetic coil assembly includes inertial dampers that can avoid excessive strain on core portions and fasteners that hold core portions of the magnetic coil together. Energy-absorbing elements are used to absorb and dissipate kinetic energy of oscillating components of the magnetic coil that result from high magnetic pressure acting on core segments. The inertial dampers and energy-absorbing elements can be selected to critically damp or overdamp mechanical oscillation in the magnetic coil assembly, allowing continuous repeated production of intense magnetic fields.

摘要： An inductor includes discrete magnetic core pieces fabricated from different magnetic materials having different magnetic properties. An inverted U-section conductive coil includes a top section and first and second legs to establish a surface mount connection to a circuit board, and the discrete magnetic core pieces are assembled around the inverted U-section conductive coil. The first and second discrete magnetic core pieces are operable to reach magnetic saturation at respectively different current loads applied to the coil when the circuit board is energized, imparting multiple steps of inductance rolloff response to a range of current loads.
