- Since this is mainly a chemical reaction, magnetic fields don't affect it much... however, ionizing radiation (e.g., X-rays) can affect the film (the amount of radiation required for this depends on the film's ASA rating... the higher the ASA rating, the more photosensitive it is).

- NO. Your question suggests you confuse elecromagnetic sensitive material like audio or video tape with light and chemically sensitive material like film. Film is not affected by electromagnetic fields but by Xrays.
Light and Energy - How Photographic Film Works
- https://electronics.howstuffworks.com/film2.htm
- Infrared light is also invisible, but if it is strong enough our skin detects it as heat. It is the energy in each photon of light that causes a chemical change to the photographic detectors that are coated on the film. The process whereby electromagnetic energy causes chemical changes to matter is known as photochemistry.

- It has a magnetic catch, and the magnet is significantly strong. When you get the flap metal within about 1/4 inch of the magnet, it snaps closed, firmly and tight, with a noticable click sound. This may not be the perfect proof, but I think it is appropriate, and an approximate answer you are looking for.

- A bulk-like performance magnetic film to MEMS was implemented by alternately sputtering of NdFeB as a main material and Ta as a barrier material. Fig. 10.3.2 shows a cross-sectional scanning electron microscopy (SEM) image of about 20 μm of NdFeB/Ta film, consisting of 40 layers, where each layer consists of 0.38 μm NdFeB and 0.01 μm Ta. By using radiofrequency …

- More often than not, magnetism will cause a watch to gain time, but it can also cause it to lose time or potentially stop. A medium to strong charge will pull these pieces in different directions, potentially slowing down cogs or bringing them to a halt. The balance spring, or hairspring as it’s also known, is usually the key cause for concern.

- Magnetism being present in everyday life poses no real threat, but it can affect our mechanical timekeepers, causing rather unwanted reactions. General everyday contact with these devices isn’t going to cause your beloved wristwatch any real harm, but overdoses of magnetism may still present a problem, causing erratic timing and even stoppage ...
How Does Magnetism Affect a Watch? - Unauthorized Access
- https://www.timesticking.com/how-does-magnetism-affect-a-watch/
- A mechanical watch affected by magnetism remains magnetically charged even after being removed from the magnetic source. This may cause a gain or loss of time. A watch can remain magnetically charged for a long period so it is recommended that you demagnetize it in order to improve accuracy. In general, magnetism has no effect since there are ...
