Chain mail reverses the Hall effect

Multimedia Mail for the Digital Study Hall

Basic education has been listed as a priority of development efforts in poor regions around the world [1]. Distance learning has significant potential for enhancing basic education, and the benefits of information and computer technology can provide an efficient means for deploying a distance learning system. Such a system, dubbed the “Digital StudyHall,” is proposed by Wang, et. al. for deploy...

The Quantized Hall Effect

The quantum Hall effect

most physical phenomena that occur in nature. Its basic equation, the Schrödinger equation, accurately describes the electronic properties of solids—of great importance in modern technology.To describe the behavior of particles that travel near the speed of light, such as neutrinos, the theory must be modified to take Einstein’s theory of relativity into account. This was accomplished by physic...

The Hall Effect

In 1879 E. H. Hall observed that when an electrical current passes through a sample placed in a magnetic field, a potential proportional to the current and to the magnetic field is developed across the material in a direction perpendicular to both the current and to the magnetic field [1]. This effect is known as the Hall effect, and is the basis of many practical applications and devices such ...
