You might be familiar with magnetic sensors. However, you might not be too familiar with Hall effect current sensors. Watch this video to learn what Hall effect current sensors are and how they work. Magnetic sensors are solid-state devices that are gaining popularity because of their adaptability and versatility in various applications.
Hall effect current sensors are a great example of a magnetic sensor gaining interest recently. A discovery by Edwin Hall, who did his work in the 1870s, states the Hall effect is the phenomenon that occurs when a magnetic field is used to produce a measurable voltage.
A thin slice of rectangular p-type semiconductor material is the primary component of a Hall effect current sensor. The magnetic flux lines exert a force on the semiconductor material, which causes the charge carriers, such as electrons and holes, to deflect to either side of the semiconductor slab after placing the device within a magnetic field.
The accumulation of these charge carriers results in a potential difference between the two sides of the semiconductor material. The potential difference occurs because of the movement of electrons and holes in a sideways direction.
