The magnetism of a product is calculated in Tesla or Gauss units.
The modern version of the Gauss Magnetometer is called the Gauss Meter. Gauss meters can measure the direction and strength of (relatively) small magnetic fields. For larger magnetic fields, the Tesla Meter is used, which is similar, but it measures in larger units of Tesla. A Gauss meter consists of a gauss probe/sensor, a meter, and a cable connecting the two. The Gauss meter works based on the Hall effect discovered in 1879 by Edwin Hall .
A pioneer in magnetic field research, Carl Freiderich Gauss (1777-1855), is also widely considered one of the greatest mathematicians. One of the first devices that could be used to measure the direction and strength of any magnetic field was developed by him – the magnetometer. He also developed a system of units for measuring magnetism and in his honor the modern unit for magnetic induction or magnetic flux density in the metric system (CGS) is called GAUSS.
The basic unit of magnetic flux in the SI system of measurement is TESLA (named after Nikola Tesla, father of electricity) and 1 TESLA = 10000 GAUSS.

How does a magnetic meter work?
The most important part of the Gauss Meter, the Hall probe, is usually flat to best measure the transverse magnetic field. Some probes are axial or cylindrical and they are used to measure fields parallel to the probe, e.g. the magnetic field inside a solenoid (cylindrical coil becomes magnetic when current is applied). run over them).
The meter uses a probe to send a test current through the wire, and due to the Hall Effect, a voltage is generated, which the meter then records. When voltage fluctuates and is rarely static, the meter usually stops the readings at a specified value and records them, along with the highest voltage value detected. Some Gauss Meters can also differentiate between AC and DC fields as they automatically calculate the RMS (root-mean-square) of the AC fields.
Above is the most common way to use Gauss Meter. Most magnets have pre-measured ratings, but researchers, electricians, educators, product designers, and several others find Gauss Gauges useful when developing or working in project.

Application of magnetic meter?
A Tesla/Gauss meter can be a useful device for measuring magnetic field strength, and some can even measure polarity direction. A simple voltage tester is actually also a type of gauss meter, as it detects the current produced by a magnetic field. Gauss meters can be used to measure:
✔️ DC and AC magnetic fields (40~500Hz)
✔️ N/S polarity of DC magnet
✔️ Residual magnetic field after machining mechanical parts
✔️ Magnetic field strength in magnetic applied products
✔️ Residual magnetic field is generated due to stress after processing stainless materials
✔️ Magnetic force of magnetized materials
✔️ Natural magnetism of steel products
✔️ Magnetic fields of motors and other household appliances
✔️ Magnetic field strength of permanent magnets
✔️ Detect leaky magnetic fields generated from superconducting magnets
✔️ Simultaneously measure Temperature along with magnetic field intensity
Industrial uses of Gauss Meters include accurate and repeatable measurements of magnetic strength involving the use of permanent magnet techniques and any ferromagnetic components. The Gauss meter allows non-destructive measurement of magnetic fields in the case of DC or AC Motors, loudspeakers, magnetic circuits or components such as relays, magnetic switches or coils, magnet classification and even for magnetic fields/ leakage/residual or stray magnetic fields. They can also be used successfully to determine whether any static or dynamic electromagnetic fields are affecting the operation of precision electronic devices at their installation location.
We hope you find this information useful. As we can see magnetic testing of products is essential in assessing quality standards, with many factors at play in each example of machinery installation. Because of this level of variation, there is rarely a “one size fits all” solution for your business health monitoring needs.
To achieve that goal, We at SEMIKI welcome the opportunity to speak with you about your magnetic measurement solution concerns and would be happy to help you plan how to address critical assets and improve your condition monitoring strategy. your overall.
