Question

What is the strongest magnetic field possible ? Is there a limit ? ​

Answer 1

Well, in the classical theory of electricity and magnetism, no, there is no upper limit on the strength of a magnetic field.

Answer 2

Explanation:

Although there is a limit of 500,000 Gauss, this is only a limit set by practicalities of working in the field of magnetic fields. This is a limit that has to be adhered to in order to stay safe around the heavy machinery and anything else that it near the machine that creates the magnetic fields.
