Abstract
PURPOSE: To enable the production of magnetic field suitable for the drive of magnetic bubble with a simple control, without using resonance capacitor, by flowing the current changed in polygonal line shape with time to the rotating magnetic field generating coil.
CONSTITUTION: The coils 3X, 3Y produce the magnetic field respectively toward X and Y axes. When the switch 1X only is ON at time t0, current flows from the voltage source 4X to the coil 3X and it increases linearly. At the time t1, when the switch 1X is OFF and the switch 2X is ON, the current ix is maximum. As a result of the switch control, the coil 3X, terminal A and voltage source 5X are connected, and the voltage source 5X has the same absolute value as 4X and outputs the negative voltage and ix is minimum at the time t3. On the other hand, the current iy of the coil 3Y is delayed to ix by 1/4 period and follows similar process. As a result, the vector of the magnetic field produced by the coils 3X, 3Y shows a square.
