Magnet
In space and astronautical engineering, a magnet is a material or object that produces a magnetic field. Magnets are used in various space applications such as magnetic torquers for attitude control of spacecraft, magnetic shielding to protect sensitive equipment from external magnetic fields, and magnetic levitation for propulsion systems. The magnetic field produced by a magnet can interact with the Earth's magnetic field, which can cause disturbances in the spacecraft's trajectory. Therefore, it is important to carefully design and test the magnetic systems used in space. Magnets can be permanent or electromagnets, which are powered by an electric current. Electromagnets are often used in space applications because they can be turned on and off, allowing for greater control over the magnetic field. Magnetic materials used in space applications include neodymium, samarium-cobalt, and alnico.
