What is the SI unit of magnetic flux density used in MRI?

Explanation:
The key idea is that magnetic flux density, which describes how strong the magnetic field is at a point, is measured in tesla in the SI system. MRI relies on a strong, uniform main magnetic field (the B0 field), and its strength is commonly stated as 1.5 T or 3 T. Gauss is an older, non-SI unit and is much smaller (1 tesla equals 10,000 gauss). Weber measures magnetic flux, not flux density, and Henry measures inductance. So the SI unit used to describe the magnetic field strength in MRI is tesla.
