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.
2. You can also solve a system of linear equations using the solve function, the simult function in the matrix menu, or use the rref function in the matrix menu. Example: Solve the system of equations: E. Solving Equations. The TI-89 is a powerful tool and can solve many types of equations.
