What is the strongest magnetic field possible? Is there a,
Aug 21, 2014· When a magnetic field gets stronger than about 500,000 Gauss, objects get ripped to pieces by the intense forces. For this reason, scientists cannot build a machine that creates a magnetic field stronger than 500,000 Gauss and survives longer than a fraction of a second. Strong enough magnetic fields therefore destroy objects as we know them.Strong Magnetic Field - an overview | ScienceDirect Topics,In MRI a strong magnetic field is applied over the subject that is to be scanned.
