1tesla

1tesla is a unit of magnetic flux density in the International System of Units (SI). It is named after Nikola Tesla, a Serbian-American inventor and electrical engineer. One tesla is defined as one weber per square meter (Wb/m²). This means that if a magnetic field has a strength of 1 tesla, it will exert a force of 1 newton on a charge of 1 coulomb moving at a velocity of 1 meter per second perpendicular to the field. The tesla is a relatively large unit, and magnetic fields are often measured in smaller units like millitesla (mT) or microtesla (µT). For comparison, the Earth's magnetic field is typically around 25 to 65 microteslas. Stronger magnetic fields are found in applications such as MRI machines, which can generate fields of 1.5 to 3 teslas or more, and in research magnets that can exceed 10 teslas. The tesla is a fundamental unit for quantifying the strength of magnetic fields.
