To make a three phase generator you have to place a certain number of magnets on your stator and armature, all with proper spacing. Electromagnetism is as complex as dealing with waves and water, so you need to know how to control the field through your design.
1 Know if an ordered pair is a solution to a system of linear equations in two variables or not. 2  Solve a system of linear equations in two variables by graphing. 3  Solve a system of linear equations in two variables by the substitution method.  Solve a system of linear equations in two variables by the elimination method.
In a system of equations, you are asked to solve two or more equations at the same time. When these have two different variables in them, such as x and y, or a and b, it can be tricky at first glance to see how to solve them.
