Unit PT
Name petatesla
Category Magnetic Flux Density
Details A petatesla (PT) is a unit of magnetic flux density (also known as the magnetic field strength) in the International System of Units (SI). Magnetic flux density is a measure of the strength and direction of a magnetic field at a particular point in space.

One petatesla is equal to 10^15 teslas (T), where one tesla is the basic unit of magnetic field in the SI system. A petatesla is a very large unit of magnetic field, and it is not commonly used in daily applications, as most magnetic fields encountered in nature and technology are much smaller, typically in microtesla (µT) or nanotesla (nT) ranges.

Magnetic flux density is crucial in studying the effects of magnetic fields on various materials, as well as understanding the behavior of particles in the field, such as in the processes of magnetic resonance imaging, the Earth's geomagnetic field, and the magnetic fields of stars and galaxies.
