Hi Clemens, That little program is really brilliant and is just what I wanted. Thank very much and to the others who have replied regarding this subject. Regards Peter, G3LDO the best aid I know is the mini Ring Core Calculator V1.2 which is freeware http://www.dl5swb.de/html/mini_ring_core_calculator.htm It is a fantastic tool for known and unknown toroid materials. For determining the µrel of an unknown toroid you wind a few turns on it,measure the inductance,enter the inductance and the physical dimensions of the core into the program and it gives you all you want to know including µrel. And the results are really correct. Very handy with Amidon toroids,too. |
