The Tesla is the unit for magnetic field, named after inventor and physicist Nikola Tesla. It is defined as one Newton of force per Ampere of current per meter of conductor, therefore it has units of . This is an extremely large amount of magnetic field, with the strongest magnetic field in laboratories reaching about 45 Tesla, and at 16 Tesla, scientists were able to levitate a frog. Typically magnitudes found of Earth's magnetic field are in the micro to milliTesla range.
The video below shows a frog being levitated in a 16 Tesla field. For more information please see High Field Magnetic Laboratory.
