Recently, the National Aeronautics and Space Administration (NASA) is expected to launch a space probe with a cost of 337 million U.S. dollars, about the size of a washing machine. The goal is to expand human exploration of outer planets in the solar system. According to reports, the Transiting Exoplanet Reconnaissance Satellite (TESS) is scheduled to be carried by the SpaceX Falcon 9 rocket from Canavera, Florida, at 6:32 pm on the 16th. Cape Erlang launches into the sky. The main goal of TESS in the next two years is to scan and observe more than 200,000 brightest stars. Look for signs of planets orbiting and decreasing the brightness of stars. This phenomenon is also known as "transit". NASA predicts that TESS will discover 20,000 extra-solar planets (ie, exoplanets), including more than 50 planets about the same size as the Earth, and up to 500 planets within twice the size of the Earth. On the 15th, NASA’s Goddard Space Center TESS scientist Elisa Quintana told reporters that it might be possible to find planets orbiting stars that are visible to the naked eye. Therefore, in the next few years, people may be able to walk outdoors and point to a star to know that it has planets. This is the prospect. Jeff Volosin, the TESS project leader of the space center, said that it is hoped that in the next few decades, they will be able to identify where there may be life outside the solar system. Isotropic magnets are magnets with a random direction of magnetization in the magnet.

Magnet powders for isotropic magnets contain crystals in one magnet particle with a direction of random magnetization, and cannot be made anisotropic magnets when a magnetic field is applied externally during molding. In the magnetization after molding, the magnetization of the same component as the direction of the magnetization field becomes strong for the magnetization in a random direction in the crystal. Therefore, the molded body, which is an aggregate of crystals, can be a magnet having a magnetic force in the direction of magnetization
