AboutDavid Barry Expertise I have a lot of experience in most traditional forms of photography, so I`m quite knowledgeable about things like camera types and formats, techniques, exposure, film types, colour, filters, lighting, standard colour and black and white developing and printing.
I do not make recommendations about brands or models, and I am not a camera technician so I may not be able to tell you what is wrong with your equipment if it`s not working .
I also know a little about digital photography and imaging with scanners and digital cameras, so ask me and I will answer if I can.

Question Will film cameras (not digital) have their existing pictures erased or damaged if exposed to a strong magnet?
Answer Reasonable question. I think I can understand why you might ask such a question. There is a silver halide compound in film, and silver is a metal.
But I believe that a film image is NOT likely to be affected by magnetism (if anyone wishes to correct me I will be interested - maybe one of the other experts would know for certain).
Film pictures are not magnetically formed like digital images.
Film works based on chemical action, not magnetic action.
It's possible, however, that some of the mechanisms and electronic functions of a film camera may be affected by magnets, although I have never personally experienced such. but then I've never actually put my camera in the field of a sufficiently strong magnet.
