do mosfets suffer from magnetic fields

pointy · 7th March 2010, 10:15 AM

i have some buz80's that will be near to the output transformers in an amp build.
so i was wondering will they suffer from the magnetic field and if so how ?

I would have thought that induced currents would be minimal due to the output MOSFET's having a low inpedance o source & drain.

However care should be taken with longs leads to the gate connection.

i'm in luck my base fly leads run full away from the transformers. thanks !
