Hi, I am a freshman in high-school and I was wondering if magnets can cause any long term affects like cancer or some other type of disease. I would like to hear back. Thank you for your time.
Answer 1:

In short, no. There is no evidence that magnets or magnetic fields cause cancer or other diseases. People with pacemakers, or other electronic implanted medical devices should avoid strong magnetic fields, but that's because the equipment can fail.

There have been a few reports of magnets actually being used to treat cancer or associated pain, but in general, these ideas are not well-established and no major medical group supports them. In general magnets are harmless to us.
