What is the SI unit for magnetic flux density?

The SI unit for magnetic flux density is called the tesla, which is symbolized by the letter T. One tesla is defined as the field intensity of 1 newton of force per ampere. One tesla is equivalent to 1 weber per square meter.

The tesla is named after the inventor and engineer Nikola Tesla, who discovered the rotating magnetic field. The tesla is used for work involving strong magnetic fields. Since most magnetic fields are not strong enough to equal 1 tesla, the microtesla is often used instead.

The non-SI alternative to the tesla is the gauss; it is often utilized for small magnetic fields.
