Effects of electromagnetic fields
Induction crucible furnaces for melting of ferrous and nonferrous metals

The mechanisms for transforming magnetic energy into thermal energy have not yet been fully popularized, although they were established as early as 1830, based on Oersted's work.

It was Maxwell, Faraday and Lenz who most precisely defined the main laws of electromagnetism. Maxwell's equations allow us to calculate all electromagnetic phenomena. Faraday's and Lenz's laws explain and demonstrate them.

These phenomena are known respectively as electric field, magnetic field, electric induction and magnetic induction.
