- Why is mutal inductance rising with the rise of current?
- Relevant Equations
- M=N2*Ф12/I1
My frient had an experiment in lab. They measured the mutal inductance on two coils wraped around one feromagnetic core.
When the current of the first coil was 1, 2, 3, 4, 5 mA the mutal inductance was 94 mH. Then they were told to rise the current to 10 mA, the mutal inductance went to 160 mH. The frequency was 50 Hz all the time.
