There is no strict definition of the term "High Magnetic Field." It has been proposed to use this term for magnetic fields that are technically difficult to generate and therefore need special equipment or large resources. Static fields above 20 T are apparently high magnetic fields in this sense, but in the case of pulsed field 40 T is easy to obtain and any field lower than this approximate limit should not be considered as "high." When a static field is used for materials processing, even 10 T is considered as "high" because the long-term use of a conventional superconducting magnet is...
