Magnetic Flux Density Converter

About This Tool

This Magnetic Flux Density Converter is a fundamental tool for working with magnetic fields in physics and engineering. It converts units of magnetic flux density (B-field), which is a measure of the strength and direction of a magnetic field. The base unit is the tesla (T).

The B-field can be thought of as the density of magnetic field lines in a given area. It is used to characterize permanent magnets, electromagnets, and the Earth's magnetic field. This tool is essential for applications ranging from MRI machines to particle accelerators.

Tips & Features

• The Tesla (T): The tesla is the SI unit of magnetic flux density. One tesla is defined as the field intensity generating one newton of force per ampere of current per meter of conductor.
• Gauss (G): The gauss is the corresponding CGS unit. One tesla is equal to 10,000 gauss. The gauss is still widely used, especially in the United States and in the context of permanent magnets.
• Earth's Magnetic Field: For context, the Earth's magnetic field is very weak, typically ranging from 25,000 to 65,000 nanoteslas (or 0.25 to 0.65 gauss). The magnets used in MRI machines are extremely powerful, often in the range of 1.5 to 3 teslas.
