@kaiserwilhelm A Tesla, T for short, is a unit of magnetic field. Another unit of magnetic field is a gauss. A refrigerator magnet is 100 gauss, a strong refrigerator magnet. The typical strength of the Earth's magnetic field at its surface is around a half a gauss. So those are everyday units of magnetic fields. There are 10,000 gauss in one Tesla.
