The document presents information about the Hall effect. It discusses how a transverse electric field is generated when a conducting material carrying a current is placed in a perpendicular magnetic field, known as the Hall effect. It was discovered by physicist Edwin Hall in 1879. The Lorentz force equation is provided. The Hall voltage generated is directly proportional to the current, magnetic field strength, and inversely proportional to the charge carrier density and thickness of the material. Applications of the Hall effect include clamp-on sensors, power sensing, position sensing, and automotive ignition. The significance is that it demonstrates the direction of electron flow in conductors.

2.  Hall effect is a process in which a transverse
electric field is developed in a solid material
when the material carrying an electric
current is placed in a magnetic field that is
perpendicular to the current.

Application of Hall Effect

8. • Hall Effect describes an important difference between positive and
negative charges that is positive charges will move in one direction
NAD negative charges will move in opposite direction of negative
charges.
• Hall effect proves that current in the metals produced due to the motion
of electrons.
