Question

How Can you prove that the forest a magnet is case of a bar magnet is always stronger the pole

Answer 1

The strength of the Earth's magnetic field at the poles is around 0.6 gauss – much weaker than a neodymium magnet! ... If we assume the Earth is a permanent magnet instead of a ball of half-molten iron with electrical currents running through it, we might figure Brmax is about 1 gauss.
