A SQUID magnetometer detects and measures magnetic fields generated by electric current, converting them into an electronic signal and producing a topographical map. It is used in medical applications, such as magnetoencephalography to map the function of neurons and magnetic cardiography to diagnose heart conditions. The equipment is contained within a cryogenic chamber cooled by […]
Magnetometers measure magnetic fields and can determine strength, orientation, and direction. They have various uses, including studying the Earth’s magnetic field, identifying archaeological sites, and detecting potential hazards for vessels. They can also provide information about the development of the Earth and Universe. Magnetometers come in different sizes and designs, with some being portable and […]
Proton magnetometers detect changes in magnetic fields by detecting proton activity and are used in various applications, including archeology, mineral exploration, ship navigation, and space exploration. They can identify ferrous materials and are often used to locate wrecks and other objects. They can also provide information about planets and other formations in space. A proton […]
A fluxgate magnetometer detects changes in the Earth’s magnetic field and is used by archaeologists, engineers, geologists, and the military to detect underground or underwater objects. It measures both the magnitude and direction of the field using two ferromagnetic cores and two coils of wire. Victor Vacquier invented it in the 1930s, and it was […]
A vibrating sample magnetometer (VSM) measures magnetic properties of materials using a vibrating component that generates an electric field in a coil. The electromagnet is activated before the test, and changes in the magnetic field are analyzed to determine magnetization. The VSM includes a device for holding the sample, a control unit, and a computer […]
