A Gauss is a common unit of measurement of magnetic field strength named after German mathematician and physicist Johann Carl Friedrich Gauss. Gauss meters are used to measure electromagnetic fields (EMF) from wiring or power lines, magnetic fields around critical equipment or to measure magnetic shielding performance. It is also commonly used to monitor radiation levels near power lines, electrical appliances, industrial devices, and electrical circuits.
Two types of gauss meters exist: scalar and vector. The scalar gauss meter measures the strength of a magnetic field present in the area around the device. The vector gauss meter measures the direction of the magnetic field depending on where the device is and which direction it's pointing. A gauss meter may combine both of these technologies.
Importance of Calibration
Sensitive measuring equipment such as gauss meters periodically require calibration to continue to give valid readings. Incorrect readings are not always obvious and can result in lost time and effort. The calibration process involves adjusting the meter in reference to a magnet with a known flux density, ensuring the highest degree of accuracy possible.
• Measure the strength of the magnetic field around power lines.
• Measure the strength of ambient magnetic fields within homes/businesses.
• Measuring and detecting if residual magnetism exists during or after the manufacturing process.
• Used in space exploration for determining more about the magnetism of foreign planets and other bodies in space.
• Used in geophysics, to detect landscape formations to help obtain information on how land area's are laid out. and get an
• In detection of hidden items such as shipwrecks

• These meters are also gaining popularity in cell phones as well. A phone utilizing this technology can point out directions to the user much like a compass does. It also may be used to let the user interact with the phone without actually touching it. Though still in the beginning stages of development, a magnet can be used to interact with the magnetometer in the phone. The magnetometer can pick up information about how the user is turning or moving her hand and then the phone responds to these movements.
