A term gaussmeter refers to the modern and contemporary version of a gauss magnetometer. It is an electrical device that measures and computes the magnitude of the intensity of a magnetic field and its direction. This device comes with a meter, a gauss probe or sensor, and a cable that joins or connects the two components. It works on the principle and basis of the phenomenon of the Hall Effect discovered by Edwin Hall in 1879. In this blog, you will know What is meant by the Term Gaussmeter.
A gaussmeter works solely on small-sizes, narrow, and constricted magnetic fields. It cannot estimate the required parameters for the large ones. Suppose a person wishes to compute the intensity and direction of a magnetic field that spreads over an extended area or region. In that case, they would require the help of a teslameter that takes the readings and measurements in the larger units of tesla.
Thus, both a teslameter and a gaussmeter are electrical instruments that can estimate and measure magnetic fields of exceedingly high intensity. Namely, they are the NMR sensors and Hall Effect sensors. Hall Effect gaussmeter can calculate the said parameter in one or more (a maximum of three) directions of the Earth’s field.
What is Hall Effect?
Hall Effect refers to the presence or generation of a voltage difference across a current-carrying or conducting material, coil, or wire. The phenomenon runs transversely to the electric current in the conductor. In addition to that, Hall Effect can operate on a magnetic field that gets applied perpendicular to the current.
Hall Effect becomes observable or noticeable in a perpendicularly applied magnetic field. It runs or moves across voltage contacts on the boundary or the edge of a metal plate or a semiconductor. In this case, it represents and displays the apparent reversal or change in the sign. It occurs in contrast to the typical and standard Hall Effect. In such instances, Hall Effect depends only on the effect of the current induced from within the void.
Hall Effect has a few parameters on which it depends. A change in them will affect the overall value or magnitude of the phenomenon. Based on the relation with the factors, it comes out to be directly proportional to the current flowing through the conductor and the strength of the magnetic field in question. Additionally, it is inversely proportional to the thickness or width of the conductor and the density in charge.
What are the Applications of a Gaussmeter?
A gaussmeter is an exceedingly beneficial electrical device that measures and computes the strength of a magnetic field. It can even estimate the direction of its polarity. It finds application in multiple domains, industries, sectors, and other places. It also has the ability and capability of acting merely as a voltage tester. It can detect the flow of electricity that gets produced due to a magnetic field.
A few applications of a gaussmeter consist of the following:
- A gaussmeter helps to measure the North and South polarity in direct current (DC) magnets.
- It computes the magnetic field intensity present in permanent magnets.
- It aids in detecting the magnetic field generated and produced from and due to superconductive magnets.
- A gaussmeter can measure the value or magnitude of the magnetic field of almost all home appliances and motors.
- It helps estimate the direct current (DC) and the alternating current (AC) magnetic field in the approximate range of 40Hz to 500Hz.
- It aids in computing the value of the residual magnetic field that remains after processing methods and procedures of mechanical parts.
- A gaussmeter allows for the estimation and measurement of the magnetic field intensity. It does so in products that get used in magnetic applications or related areas.
- It gauges the magnitude of the magnetic force given off by or generated from magnetizable substances and materials.
- It also determines the residual magnetic field produced from the stress generated after stainless steel product processing.
- A gaussmeter can find and discover the natural magnetism of a colossal number of steel products.
- It can measure the temperature of a magnetic substance along with the intensity of its magnetic field simultaneously.
- It can compute, regulate and control the strength of a magnetic field of various household machines and appliances for safety purposes.
In addition to all these applications, a gaussmeter gets used for many more different and diverse purposes. For example, the electrical device helps detect the presence and measure the value of electromagnetic radiation in residential places or areas close to where people live and work. The calculated magnitude gets compared against the limits of safety standards set by numerous global regulations and directives. Accordingly, the required steps of protection and hazard control get taken.
What does the Industrial Application of a Gaussmeter Indicate?
A gaussmeter is an exceedingly common electrical appliance or device used in industries for multiple purposes and intentions. It finds application in almost all sectors, be it the automobile one or Information Technology.
In the industries, a gaussmeter gets used for the primary objective and goal of obtaining repeatable and exact measurements of the strength or intensity of a specific magnetic field. In most cases, the computation relates to the technical usage and working or ferromagnetic constituents, components, and substances or associated with permanent magnets. In other words, it helps take and deliver accurate and precise results of the parameters for the sake of convenience and equipment performance, and utility.
A gaussmeter allows for the non-destructive computation of a magnetic field associated with alternating current or direct current appliances. These can consist of loudspeakers, motors, magnetic circuits, and even magnetic components like switches, coils, or relays.
A gaussmeter can classify the various types of magnets. It also helps distinguish between the measurement of stray or residual leakage of magnetic fields.
Additionally, a gaussmeter can get used to determine the effect of any dynamic or static electromagnetic fields accurately and successfully. It does so for the operation and efficiency of a particular electronic device at its installation place.
