The design of ORBUMP magnet is based on new high flux density
Ni-Zn CMD10 ferrite material.
The saturation flux density is in the range 0.41 – 0.46 T. It helps to
generate 0.28 T field in the magnet air gap with quick field decay. The
equivalent frequency is up to 10 kHz.

What is needed:

  1. AC measurements of symmetrical hysteresis loops.
  2. AC measurements with DC bias field to generate single polarity
     pulses.
  3. DC measurements of main and single polarity B-H curves.
  4. Measuring the total power losses in ferrite material.
  5. Calculate the hysteresis losses in ferrite.
  6. Measure the temperature dependence of B-H curves in the
     temperature range of 20-60 C.
  7. Measure the ferrite volumetric resistivity.
  8. Ferrite high voltage test.
