Can someone point me in the direction of an equation to determine magnetic force at a given distance? I'm trying to determine what percentage of magnetic attraction or repulsion remains at a separating distance of 1cm, 2cm, 3cm, etc... Thank you.
I've been trying to learn more about inductive heating to try and answer a few questions of mine concerning the amount of heat generated by magnets passing through opposite magnetic fields at a high frequency. Does inductive heating heat from the inside of a conductive material outward, or does...
If two neodymium magnets were held north to south with 1cm separating them, how quickly would they demagnetize under the following conditions:
- Average temperatures (say -10 to 130 degrees F at the
extremes)
- Exposed to air
- high pressures (possibly spiking to as much as 400psi)...
I've been doing some searching and I've found some information that seems to suggest that magnets exert a slightly higher attractive force than their repulsive force, when dealing with two identical magnets. For example, two magnets placed N to S would exert more force on each other...
