Magnetic flux density, also known as magnetic induction, is a fundamental physical quantity used to describe the strength and direction of a magnetic field. It represents the amount of magnetic flux passing through a unit area perpendicular to the magnetic field. The unit of magnetic flux density is the Tesla (T) in the International System of Units (SI), but it can also be expressed in other units, depending on the region or application.
The Magnetic Flux Density Converter is a useful tool for converting between different units of magnetic flux density. This calculator can help you easily convert values between Tesla (T), Gauss (G), Weber per square meter (Wb/m²), and other related units used in electromagnetism.
What is Magnetic Flux Density?
Magnetic flux density is a vector quantity that measures the magnetic influence at a specific point in space. It gives the amount of magnetic flux (Φ) passing through a given area (A) in a magnetic field, usually represented as:
B = Φ / A
Where:
- B = Magnetic flux density (in Tesla)
- Φ = Magnetic flux (in Weber)
- A = Area through which the flux passes (in square meters)
The Tesla is the SI unit for magnetic flux density, and one Tesla is defined as one Weber per square meter:
1 T = 1 Wb/m²
In other contexts, magnetic flux density might be measured in units such as Gauss (G), which is used in some non-SI systems.
Units of Magnetic Flux Density
Here are some common units used to measure magnetic flux density:
| Unit | Abbreviation | Definition |
|---|---|---|
| Tesla | T | The SI unit of magnetic flux density, equivalent to Wb/m². |
| Gauss | G | A non-SI unit, commonly used in the cgs system. 1 G = 10⁻⁴ T |
| Weber per square meter | Wb/m² | Equivalent to Tesla in the SI system. |
| Maxwell | Mx | A cgs unit of magnetic flux. 1 Maxwell = 10⁸ Weber. |
Magnetic Flux Density Conversion Table
Below is a table to help you convert between various units of magnetic flux density:
| Magnetic Flux Density (T) | Gauss (G) | Weber per square meter (Wb/m²) | Maxwell (Mx) |
|---|---|---|---|
| 1 Tesla | 10,000 Gauss | 1 Wb/m² | 10⁸ Maxwell |

| 0.01 Tesla | 100 Gauss | 0.01 Wb/m² | 10⁶ Maxwell |
| 1 Gauss | 0.0001 Tesla | 0.0001 Wb/m² | 10⁴ Maxwell |
| 1 Maxwell | 0.00000001 Tesla | 0.00000001 Wb/m² | 1 Maxwell |
Magnetic Flux Density Conversion Formulas
To convert between different units of magnetic flux density, you can use the following formulas:
- Tesla to Gauss:
- 1 T = 10,000 G
- Gauss to Tesla:
- 1 G = 0.0001 T
- Tesla to Weber per square meter (Wb/m²):
- 1 T = 1 Wb/m²
- Weber per square meter (Wb/m²) to Tesla:
- 1 Wb/m² = 1 T
- Tesla to Maxwell:
- 1 T = 10⁸ Maxwell
- Maxwell to Tesla:
- 1 Maxwell = 0.00000001 T
Example Calculations
Example 1: Convert 0.5 Tesla to Gauss
Using the conversion factor 1 T = 10,000 G:
0.5 T × 10,000 = 5,000 G
So, 0.5 Tesla is equal to 5,000 Gauss.
Example 2: Convert 10,000 Gauss to Tesla
Using the conversion factor 1 G = 0.0001 T:
10,000 G × 0.0001 = 1 T
So, 10,000 Gauss is equal to 1 Tesla.
Example 3: Convert 2 Weber per square meter to Tesla
Since 1 Wb/m² = 1 T, then:
2 Wb/m² = 2 T
So, 2 Weber per square meter is equal to 2 Tesla.
Frequently Asked Questions (FAQs)
1. What is the difference between Gauss and Tesla?
The Tesla (T) is the SI unit for magnetic flux density, while the Gauss (G) is a non-SI unit commonly used in the cgs (centimeter-gram-second) system. One Tesla equals 10,000 Gauss.
2. What is the practical use of magnetic flux density?
Magnetic flux density is used in various fields, such as:
- Electromagnetic design (e.g., motors, transformers, and generators)
- Medical imaging (e.g., magnetic resonance imaging, or MRI)
- Geophysics (for measuring the Earth’s magnetic field)
3. Why do we use different units for magnetic flux density?
Different fields and countries use various units for convenience or historical reasons. The Tesla is the standard in scientific and engineering contexts, but Gauss and Maxwell are still used in some applications, particularly in older systems and certain types of equipment.
4. How can I measure magnetic flux density?
Magnetic flux density is typically measured using instruments like:
- Magnetometers (to directly measure the field strength)
- Hall effect sensors (for measuring magnetic fields in circuits)
- Search coils (used in electromagnetic studies)
5. Is a higher magnetic flux density always better?
Not necessarily. A higher magnetic flux density may be needed in some applications, like in motors or magnetic resonance imaging (MRI), but excessive magnetic flux density can cause equipment malfunctions or even pose health risks. The optimal flux density depends on the specific application.
