There is disclosed herein an apparatus for electromagnetic forming of a workpiece with enhancements that increase the durability and overall efficiency of the solenoid coil. The system provides the user with a plurality of methods to enter a text file for error identification and analysis including both realtime and non-realtime input. The bio-signal detecting device is used for wearing on the body of user so that the bio-signal sensing modules can obtain a plurality of bio-signals form the user. The tissue manipulation assembly may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. The turn-on time of the power switch is detected to update the adjusting signal.
