I'm feeling a little under the weather at the moment, but here's a random fun physics fact.
Both the Earth and the Sun have magnetic fields of around a hundred microtesla. Refrigerator magnets have a slightly higher magnetic field of around a millitesla. The strongest maintainable magnetic field created in a lab is around 45 tesla. In contrast, a neutron star creates a magnetic field on the order of $10^7$ tesla. That is a very strong magnetic field.
