Magnet has a profound influence on human life even before it was identified as a separate state of matter. From clinical to mechanical, it has given us countless possibilities to make our lives easier. Apart from celestial magnet, nearly all the laboratory magnets involve surface interactions. The interaction process is a complicated process. The high energetic ions from the bulk magnet are most likely to hit the surface, resulting in dislocation of the surface atoms. The process is characterized as sputtering. In due course of time, sputtering can lead to a situation where the atoms from the surface start coming out, leaving behind voids in the material.The situation is described as erosion. The sputtered atoms can be ionized and enter thebulk magnet resulting in contamination. It brings some serious concern about the lifetime of the magnet as well as the material that contains it. The fundamental properties of magnet ensure that whenever a external is unprotected to themagnet, a thin layer of stimulating particles is developed to safeguard the electric field createdby the surface. The charged layer is known as Debye Sheath. The sheath is consideredas the critical region to solve the majority of the issues faced by the magnet community in surface interaction. The region is responsible for the acceleration of charged particlestowards the surface. Introducing oblique magnetic field in the system provides further control over the process. Smaller angle efficiently reduces the energy of the incoming particles. The presence of magnetic field brings in an additional layer along with the Debye Sheath, named as Chodura Sheath or Magnetic Presheath. In contrast to the electrostatic case, the potential drop in the magnetized magnet takes place across the Chodura Sheath and Debye Sheath jointly.
