What is Magnetic Flux Density / Field Strength?
Magnetic flux density (also known as magnetic field B) measures the strength of a magnetic field at a point in space. It represents the amount of magnetic flux passing through a unit area perpendicular to the field direction. The SI unit for magnetic flux density is the tesla (T), while the CGS unit is the gauss (G). Magnetic field strength (H) is a related quantity that describes the magnetizing force produced by electric currents or magnetic materials, with the oersted (Oe) as its CGS unit.
These measurements are fundamental to electromagnetism, electrical engineering, and physics research. Understanding and converting between magnetic units is essential for designing electrical motors, transformers, magnetic storage devices, and conducting scientific research in magnetism and materials science. The ability to convert between different magnetic units allows for seamless communication and collaboration across different systems of measurement worldwide.
For example, physicists working with superconducting magnets might need to convert between teslas and gauss, while engineers designing magnetic shielding might need to convert between oersted and tesla.

Research & Development
Materials science, superconductivity studies, magnetic field measurements. For example, converting 100 oersted to 0.01257 tesla for experimental parameters.
Manufacturing
Magnetic component production, quality control, magnetic testing. For example, converting 5,000 gauss to 0.5 tesla for magnetic material specifications.
Historical Evolution of Magnetic Measurement
Magnetic measurement has evolved from early observations of lodestones to sophisticated modern instruments. The gauss was named after Carl Friedrich Gauss, who made significant contributions to understanding Earth's magnetic field. The tesla (named after Nikola Tesla) was adopted as the SI unit in 1960, replacing earlier units and providing a standardized measurement for magnetic flux density. The oersted (named after Hans Christian Ørsted) is used primarily for measuring magnetic field strength in the CGS system.
The transition to SI units has standardized magnetic measurements globally, though CGS units like gauss and oersted are still widely used in specific applications. Modern technology allows measurements from extremely weak fields in medical applications to incredibly strong fields in research magnets, enabling our converter to handle both everyday and extreme measurements.
Frequently Asked Questions
What is the standard unit of magnetic flux density?
The tesla (T) is the SI unit of magnetic flux density, defined as one weber per square meter. It is the foundation for all SI magnetic measurements and is used internationally in scientific research, engineering applications, and industrial specifications. As the base SI unit for magnetic flux density, the tesla ensures consistency in electromagnetic calculations and international standards.
How do I convert between tesla and gauss?
The conversion factor is 1 tesla = 10,000 gauss. To convert from tesla to gauss, multiply by 10,000. To convert from gauss to tesla, divide by 10,000. Our magnetic converter tool handles these conversions automatically with high precision, eliminating calculation errors and saving time for engineers and scientists.
What's the difference between tesla and oersted?
Tesla measures magnetic flux density (B-field), while oersted measures magnetic field strength (H-field). Tesla is an SI unit, while oersted is a CGS unit. In vacuum or air, they are related by B = μ₀H, where μ₀ is the permeability of free space. This distinction is crucial for electromagnetic calculations and proper unit usage in physics and engineering.
Why are there different units for magnetic measurements?
Different units serve different contexts and historical development paths. Tesla is used for modern SI-based calculations, while gauss and oersted are retained in specific applications and legacy systems. This variety allows for convenient expression of measurements across different fields, from medical MRI machines to industrial electromagnets, making our magnetic converter tool essential for handling these diverse units.
