Do you know what smartphone navigation, contactless payments and MRI, a life-saving medical imaging technology, have in common?
\nThe answer lies in the invisible world of magnetic fields and the sensors that detect them.
\nThese fascinating forces surround us everywhere – from the Earth’s natural magnetic field, which guides the compass, to the complex systems used in advanced technology.
\nThe magnetic field sensor, a key component of many devices, allows us to interact with this hidden dimension.
\nFind out what specifically this small component is, how it works and where you can successfully use it. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Origins magnetic field sensor<\/strong><\/a> date back to the late 19th century, when American physicistEdwin Herbert Hall<\/strong> discovered the phenomenon that still bears his name – the Hall effect<\/strong>.
\nIn 1879, during his experiments at Johns Hopkins University, Hall noticed that when an electric current flows through a conductor placed in a transverse magnetic field, a voltage is generated at the edges of the conductor, perpendicular to the direction of current flow.
\nThis discovery was groundbreaking because it proved for the first time that a magnetic field could affect the flow of current in a material, opening up new possibilities in the study of magnetism and electricity. <\/p>\n

The Hall effect<\/strong> quickly found practical application, leading to the development of the first magnetic field sensors.
\nThese devices were able not only to detect the presence of a magnetic field, but also to measure its strength and direction.
\nThe development of semiconductor technology in the 20th century further contributed to the miniaturization and improved performance of these sensors, making them extremely useful in many fields of technology.
\nSince then, Hall effect-based sensors have become the foundation for many advanced applications. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Magnetic field sensor<\/strong><\/a> is a device used to detect and quantify magnetic fields.
\nIts operation is based on the aforementioned Hall effect<\/strong>, which involves generating a transverse voltage in a conductor or semiconductor through which an electric current flows when it is placed in a transverse magnetic field.
\nThe voltage is perpendicular to the direction of current flow and to the direction of the applied magnetic field, and is proportional to the intensity of the field. <\/p>\n

In practice, when a semiconductor wafer is in the presence of a magnetic field and a current flows through it, electrons in the material are deflected due to the Lorentz force, leading to a Hall voltage at the edges of the wafer. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The value of this voltage is a measure of the strength of the acting magnetic field.
\nOther types of sensors related to the magnetic field are magnetoinductive sensors, which use electromagnetic induction to detect changes in the magnetic field, and SQUID (Superconducting Quantum Interference Device), which are extremely sensitive and used mainly in scientific research. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
