Main Question or Discussion Point
Permanent magnets are advertised as having some scalar strength, say, 1.5 Teslas, depending on the composition of the magnet but not its volume. I'm confused about what this means. Shouldn't the magnitude of the magnetic field vary depending on where you measure it? And if I epoxy together two equally-oriented magnets, I would expect that the magnitude of the magnetic field, at a sufficient distance from the magnets, would be approximately twice the strength of that of one of the magnets alone.
