My question is about the strength of magnets and how the strength is affected when you spin a magnet. When I use my meter to read the gauss of a permanent magnet I don't get much of a reading at all. However, when I spin the magnet the reading becomes very strong bouncing the needle quite high or showing a high reading on a digital meter as well.
Is this truly an accurate reading or is the spinning magnet actually influencing the meter to give incorrect high readings? The main reason I ask is I'm trying to learn all I can about emf and how it affects your health and I would like to know if things such as my fish tank motor, which can give readings off the chart of my meters, are truly a potential health issue or just showing a faulty gauss.
I tried to web search but kept running into MRI websites. If someone has a link that explains this it would be very much appreciated.
Thanks.
