text: Magnets are always dipoles. Always. This is Maxwell's second law of electromagnetism (Div B = 0). The divergence of a magnetic field always equals 0.\n\nThe magnetic moment would decrease for each part of the magnet, but the sum would remain the same. Magnetic moment equals pole strength times separation distance. Each individual magnetic moment would be unchanged, but the sum for each part would be less, and the total sum would be the same.
