What Is a Tesla Meter?
A tesla meter is an instrument for measuring the magnetic field (magnetic flux density) in a space.
Magnetic flux density is the magnetic flux per unit area. It is created by the presence of magnetic poles or currents.
A tesla meter use an electrical property of semiconductors called the Hall effect to display the magnitude of the magnetic flux density in units of gauss (G) or tesla (T).
There are both handheld and stationary types, and the stationary type is generally more accurate and has higher resolution (minimum resolution of 0.1 nT), and can measure magnetic fields as strong as several 10 T.
Uses of Tesla Meters
Tesla meters are used not only for R&D and academic purposes, but also to verify the strength of magnetic fields in manufacturing and quality assurance.
For example, accelerator facilities use powerful electromagnets (~10T), and the Tesla meters are used to measure them. Another application is in product quality control, where measurements are made to determine the magnetism and magnetic flux leakage, as well as the properties of magnetic materials.
The earth also has a magnetic field (~nT), albeit a weak one, and is therefore frequently used to measure the geomagnetic field. Depending on the magnitude and type of the magnetic field to be measured, and the accuracy required, the appropriate instrument should be selected.
Principle of the Tesla Meters
In tesla meters, the Hall effect is used to measure magnetic fields. The Hall effect is a phenomenon in which an electric field is generated in a direction perpendicular to the current flowing through a semiconductor when a magnetic field is applied perpendicular to the current and the magnetic field.
The element that causes the Hall effect is called a Hall element (Hall sensor) and is used as a probe to measure the magnetic field. There are two main types of probes: transverse (flat plate) and axial (cylindrical).
The transverse type measures the magnetic field perpendicular to the flat plate. Because it is a thin plate, the magnetic field can be measured by inserting a probe even with only a narrow gap.
The axial type, on the other hand, measures the magnetic field perpendicular to the probe end face. It can be inserted into a small solenoid coil, for example, to measure the internal magnetic field.
To accurately evaluate the magnetic field using these probes, the relationship between the angle of the probe and the magnetic field to be measured, the distance between the probe and the object, and the size of the object are considered.
