WebThe chances of all hard drives using the same grade of magnet is very low. Different designs call for different grades of magnets. It is possible that some hard drives use N52 magnets but in general there is no way to tell. If it is really important for you to know the grade, you can send magnets out to be tested. WebBy adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.

WebDec 6, 2024 · Best answer will explain why electromagnets loose strength over distance by the cube of the radius distance from the magnet (as corrected by @Trevor), ways to increase the distance, possibly up to the length of a half hand and explain how to measure what can one achieve, given number of coils, current, coil density etc... electromagnetism WebJun 3, 2006 · Assuming you are stacking the magnets on top of each other (so they are in attraction), the output of the stack will be higher than the magnets individually. The amount of increase depends on the size of the individual magnets. However, a stack of two magnets will not double the output, it'll work out to be less than 2x. fisher intensifire led light kit 72560

WebJan 4, 2024 · The contact pull force for an ideal magnet with flat pole area A is F p u l l = B r 2 A 2 μ 0 For example, a 1 inch diameter cylindrical neodymium magnet with B r = 13200 Gauss would be expected to have F p u l l = 351 N = 79 pounds, and the measured value of 61 pounds for a real (non-ideal) version of this magnet seems reasonable. WebApr 26, 2024 · Stack Magnets Together One other way to make a weak magnet stronger is to stack more of them together. The stacked magnets will work as one to exert a greater magnetic force. The more magnets you stack, the stronger they will be. That is, until the length of the stack is equal to the diameter of the magnet. WebMar 2, 2024 · Here's how to start using one: Set the maximum voltage to be read at 10 volts DC. Read the voltage display with the meter away from a magnet. This is the baseline or original voltage, represented as V0. 2 Touch the meter's sensor to one of the magnet's poles. fisher interior home ltd
