Hall current sensors operate based on the Hall effect, which was discovered by Edwin Hall in 1879. The Hall effect refers to the phenomenon of a voltage difference appearing across a conductor when placed in a magnetic field and a current flow perpendicular to both the field lines and the direction of current. This effect is a result of the Lorentz force acting on the charge carriers, creating an imbalance that generates a measurable voltage.

2. Working Principles of Hall Current Sensors:

Hall current sensors consist of several key components, including a conductor, a magnetic field, and a Hall element. The conductor carries the current to be measured, while the magnetic field, either created by a permanent magnet or an electromagnet, causes the Hall effect to occur. The Hall element, typically made of semiconductor material, is positioned perpendicular to the magnetic field and the current flow.

When a current passes through the conductor, the Hall element measures the magnetic field strength and generates a proportional voltage. This voltage, known as the Hall voltage, is directly proportional to both the magnitude of the current and the strength of the magnetic field. By measuring this voltage, the current flowing through the conductor can be accurately determined.
