Week 11

19th August 2019

Searched and listed some of the materials needed for this project. Enameled copper wire will be used as the coil for they are used in the construction of transformers, inductors, motors, generators, electromagnets and other applications that require tight coils of insulated wire. Also searched for magnets, floater and beacon light.

Based on previous calculations, the number of turns of coils is unreasonable to be applied to the design. By using Neodymium magnets, this problem can be solved. Neodymium magnet is a permanent magnet made from an alloy of neodymium, iron and boron. There are many grades of neodymium magnet. The strength varies according to its grade. It is extremely stronger than industrial magnets. For example, N40 neodymium magnet has the strength of 4000T, N50 neodymium magnet is 5000T and industrial magnets are only 1T.

Made some calculations to find the number of turns of coil if N40 and N50 neodymium magnets were to be used in the system. It is proven that the number of turns of coils has decreased dramatically. Thus, proceed to searched where to purchase neodymium magnets online.
