Coronal magnetic fields are at the heart of most of the unsolved problems in solar physics and of the solar–terrestrial relationship. However, no routine measurements have been carried out for the magnetic field measurement in the solar corona, due to the weakness of its signature. In the past several decades, a number of techniques have been developed for coronal magnetic field diagnostics. In this talk, I will briefly review the methods that have been used for coronal magnetic field measurements, and then give an overview of the magnetic-induced transition, MIT method, including the physical principle, history, methodology, and examples of applications.
