Because you're Hardy Spicer, and the Universe is out to get you.

Like neutron-star strong? MRI strong? Fridge magnet?
If there's an LC tuned circuit anywhere in the signal-processing chain, your magneitc field might be high enough to saturate the core of the inductor and throw the resonant frequency way off.

LC went out with the ark. Filters are ceramic.
That still leaves ferrite beads - or rather ferrite chip inductors -; they won't do their job anything like as well if the ferrite is saturated.

How do you know this? Describe the location? Describe the field?
