**5. Applications**

Permanents magnets have many applications in everyday life from basics to high profile. The specific application of the magnets also depends on the magnetic performance of the materials at a given temperature and cost. Modern permanent magnets are important for academic research, defense applications along with energy technologies. The rare earth magnets have wider range of application in our daily life to modern technology and devices [4].

Bonding applications are common for SmCo magnets. For high temperature application specially in the field of Space, aeronautics and electric vehicle, Sm–Co-based alloys magnets are used [11, 46]. The most powerful Neodymium Rare Earth Magnets has versatile application which includes motors, sensors, mobile phones, computer hard drives and data storage industry [47–50], washing machines, refrigerators. NdFeB magnets markets are the automobile industry and energy sector. SmFeN magnets also have potential applications in electric motors, generators, actuators,

magnetic bearings, and other high-performance magnetic devices. Their high coercivity field and high saturation magnetization make them suitable for use in motors and generators that require high torque and power density.
