ZecronTech said:For example at the surface of both magnets, the field strength is 1.5Tesla. Suppose the top magnet plus the weight it's supporting is 1 Newton, what is the height that I need to separate both magnets of like facing poles so that the top magnet hovers?
sankalpmittal said:Hence classically the force between two poles of bar magnet is defined by F = Bqm. This formula is valid if the poles are mere points.
ThomasO said:What about intregrating the differential forces between differential areas on each magnet? Would it work? Do you know what I mean?
The force between two magnets can be calculated using the equation F = (μ0 * m1 * m2)/(4π * d^2), where μ0 is the permeability of free space, m1 and m2 are the strengths of the two magnets, and d is the distance between them.
The unit of force in magnetism is typically measured in Newtons (N) or dynes (dyn).
The strength of a magnet is directly proportional to the force it exerts. This means that the stronger the magnet, the greater the force it will exert on other magnets.
The force between magnets can be either attractive or repulsive, depending on the orientation of the magnets. Like poles (north to north or south to south) will repel each other, while opposite poles (north to south) will attract.
The force between magnets is inversely proportional to the square of the distance between them. This means that as the distance between magnets increases, the force decreases. Conversely, as the distance decreases, the force increases.
