Can magnetic energy be transmitted?
Yes, but in a particular medium. The simplest example is that the iron touches the magnet and is magnetized, which is passed to it by the magnet
A magnetic object will magnetize a magnetic material close to it into a magnet, and a new magnet will magnetize the magnetic material close to it...... In theory, there is no end to it. But the weaker the magnetism, the less likely it is to ignore the magnetic transmission you ask
Yes, magnetic materials are paramagnetic and diamagnetic. Ferromagnetic materials. These kinds of paramagnetic materials allow magnetic properties to pass almost the same size, and ferromagnetic materials get magnetic after they are heard
