Permanent Magnet: once magnetized, remains magnetized. Ferromagnet: easily magnetized (iron, nickel, cobalt, some rare-earth metals, magnetite). Paramagnet: magnetized with more difficulty. Diamagnet: repels magnetic fields (slightly) – “not magnetic”./Materials can be broken into smaller chunks, called “domains”. Each domain has a miniature magnetic field. Materials may look the same, but at a smaller level, domains could be different – hence why some are magnets (or magnetize easily) and Read More

2.What is a chemical reaction?
The process by which some substances, called reactants, become new substances, called products.
3.How are chemical reactions represented?
With chemical equations
