Applications of force and torque on a current carrying conductor | part 3: Hall effect

 Application of force on a current carrying loop as Hall Effect. 

The Hall effect is a phenomenon that occurs when an electric current passes through a conductor placed in a magnetic field perpendicular to the current flow. 

When a magnetic field is applied perpendicular to the direction of current flow, the moving charges experience a force called the Lorentz force. 

• This force pushes the charges to one side of the conductor, creating an electric field perpendicular to both the current and magnetic field.
  
• As a result, a voltage difference, known as the Hall voltage, is generated across the width of the conductor. 
  
• The Hall voltage is directly proportional to the strength of the magnetic field and the current flowing through the material, as well as inversely proportional to the thickness of the conductor.

Applications of Hall Effect 

The Hall effect can be used to measure various properties of a material, such as:

1. its magnetic field strength
   
2. charge carrier density
   
3. mobility. 
   

• It is commonly used in devices like Hall effect sensors and magnetometers.
  
• The Hall effect plays a significant role in understanding the behavior of electrons in various materials, including semiconductors. 
  
• It helps in characterizing the electrical conduction properties of different materials and has important applications in fields such as electronics, physics, and material science.
