CHAPTER II. REVIEW OF THE RELATED LITERATURE
A. Temporary Magnet
Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are utilized as a part of phones and electric engines in addition to other things. The materials which are utilized as incited magnets are dealt with as temporary magnets as they are magnetized for a brief length of time when pulled in by a solid or permanent magnet which charges them. For example, when a …show more content…
Copper is the one who is the most ductile metals. Copper is essential for a various metal alloys such as coins, thermocouples and etc. Copper is essential mostly in some living organisms as the trace dietary mineral. Copper lies below the hydrogen in the electromotive series which it is not soluble in acids with the changes in hydrogen then it will react with oxidizing acids, such as hot and nitric. (The Editors of Encyclopædia Britannica, 2018).
Brass, it is also an alloy it was made by a cooper and zinc in these two types of elements brass can be harder and more soften alloy and it can improve also some machine ability and corrosion resistance (Terrence Bell, 2017). Tin is the one who helps brass to make it stronger and ductile. According to the hardness, this alloy brass incorporates brings semi-hard and hard metal composites. This characterization relies on the execution of weight required for newly develop shaped metal. Contingent upon the measure of zinc, there is red and yellow metal ("BCFA",
