15T

15T is an abbreviation commonly used to denote a magnetic field strength of 15 teslas. The tesla (T) is the SI unit for magnetic flux density, equal to one weber per square meter.

In science and engineering, 15 T magnets are used in high-field research for applications such as nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI). Higher magnetic fields can improve signal strength and resolution in both NMR and MRI. Clinical MRI typically operates at 1.5 or 3 T; research systems may reach 7–11 T or higher, and 15 T magnets exist in experimental settings but require specialized facilities, safety measures, and infrastructure.

Beyond physics and instrumentation, 15T can appear as a model designation, project code, or part number in various industries. In such cases, its meaning depends on the manufacturer and context, and it is not universally standardized.
