Magnetic Flux Density Converter

Magnetic Flux Density Converter

One gauss equals one ten-thousandth of a tesla. Our converter handles gauss and tesla, plus other magnetic flux density units. Fast, accurate, no sign-up required.

Magnetic fields in plain language

A magnetic field is the invisible influence that steers compass needles, sticks magnets to a fridge, and lets motors and generators work. Engineers measure how strong that field is at a point in space using quantities that evolved in different countries and eras—hence multiple unit names for the same physical idea.

Magnetic flux density describes how concentrated the magnetic effect is through an area (think "how packed" the field lines are). The modern SI name for that is the tesla; older texts and some industries still quote the gauss. Converting between them is a fixed ratio, like inches to centimeters.

Millitesla and microtesla are convenient for Earth's field, small sensors, and medical imaging magnets that are strong but not stated in whole teslas. Use the lists below once you are comfortable with the vocabulary above.

Key Units

• Tesla (T): SI unit of magnetic flux density B; 1 T = 1 Wb/m² = 10⁴ G; standard in physics and engineering.
• Gauss (G): CGS unit of flux density; 1 gauss = 0.0001 tesla; common in magnetics and older papers.
• Wb/m² (weber per square meter): Same as tesla; flux density as flux per unit area.
• Wb/cm², Mx/cm²: Alternative area-normalized flux density units in CGS and mixed systems.
• Millitesla (mT), Kilogauss (kG): Practical scales for motors, sensors, and Earth's field.

Supported Unit Categories:

• SI Units: Tesla (T), Millitesla (mT), Microtesla (μT), Nanotesla (nT), Picotesla (pT)
• Practical Units: Kilotesla (kT), Megatesla (MT)
• CGS Units: Gauss (G), Milligauss (mG), Microgauss (μG), Kilogauss (kG)

Key Concepts:

Magnetic flux density (B) is a measure of the strength and direction of a magnetic field at a specific point. It's measured in teslas (T) in the SI system and gauss (G) in the CGS system. The tesla is defined as one weber per square meter, representing the magnetic flux density that produces one volt of electromotive force in a conductor of one meter length moving at one meter per second perpendicular to the magnetic field.

Relationship to Other Magnetic Quantities:

Magnetic flux density is related to magnetic flux (Φ) through the relationship: B = Φ/A, where B is magnetic flux density, Φ is magnetic flux, and A is the area perpendicular to the magnetic field. It's also related to magnetic field strength (H) through the material property of permeability (μ): B = μH.

Typical Values:

• Earth's Magnetic Field: 25-65 μT (0.25-0.65 G)
• Refrigerator Magnet: 5-10 mT (50-100 G)
• MRI Machine: 1.5-3 T (15,000-30,000 G)
• Neodymium Magnet: 1-1.4 T (10,000-14,000 G)
• Laboratory Electromagnet: 2-10 T (20,000-100,000 G)

Design Considerations:

When designing electromagnetic devices, the required magnetic flux density depends on the application requirements, material properties, and efficiency considerations. Understanding the relationship between different units helps engineers optimize designs for performance, size, and cost. The choice between SI and CGS units often depends on the specific industry and application standards.
