To convert from Tesla (T) to Gauss (G), you multiply by 10,000, as one Tesla is equal to 10,000 Gauss.
Example:
An MRI machine operates with a magnetic field of 1.5 T. Convert this to Gauss.
1.5 T * 10,000 = 15,000 G
Answer: 1.5 Tesla is equal to 15,000 Gauss.
Magnetic flux density, commonly referred to as the B-field or simply the magnetic field, is a vector field that describes the magnetic influence in a region of space. It is a measure of the strength of a magnetic field at a given point, as well as its direction. The B-field is what exerts a force on moving electric charges (the Lorentz force) and on magnetic materials. It can be visualized as lines of flux; the density of these lines in a given area indicates the strength of the field. A strong magnetic field, like that near a neodymium magnet, will have densely packed field lines, while a weak field, like that of the Earth, will have sparse lines.
The B-field represents the *total* magnetic field in a region, resulting from both external electric currents and the internal magnetic response of any materials present. This distinguishes it from the magnetic H-field, which only represents the field from external currents. The SI unit for magnetic flux density is the Tesla (T), named after the brilliant inventor Nikola Tesla. An older, smaller unit, the Gauss (G), is also still commonly used, particularly in the United States and in certain applications like geology. This converter is essential for physicists, engineers, and scientists working with magnets, motors, MRI machines, and particle accelerators, allowing for easy translation between these common units.
F = q(E + v × B). The magnetic component of the force is F = q(v × B).F = I(L × B). This is the principle behind electric motors.Φ = ∫ B ⋅ dA. For a uniform field perpendicular to the surface, this simplifies to Φ = B × A.One Tesla is a very powerful magnetic field. The strong neodymium magnets used in many consumer products can have a field of around 1-1.4 T at their surface. Medical MRI machines typically operate at 1.5 to 3 Teslas. The Earth's magnetic field, by comparison, is only about 0.00005 T.
A Gauss (G) is a smaller unit of magnetic flux density. One Tesla is equal to 10,000 Gauss. The Earth's magnetic field is roughly half a Gauss. The Gauss is often used in geology and in some industrial applications.
The B-field (magnetic flux density) represents the total magnetic field within a material, including the material's own response. The H-field (magnetic field strength) represents only the external magnetizing force from electric currents. While they are proportional in a vacuum, they are different in magnetic materials. The B-field is used to calculate the actual force on a moving charge.
Nikola Tesla was a Serbian-American inventor, electrical engineer, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electrical system. His work was revolutionary and formed the basis for much of modern electrical technology. The SI unit of magnetic flux density is named in his honor.
An electric motor works on the principle of the Lorentz force. An electric current is passed through a coil of wire inside a magnetic field. The magnetic field exerts a force on the wire (F = I(L × B)), causing the coil to rotate and turn a shaft, thus creating mechanical work.
