I've been trying to reverse the polarity of a magnet without any success. I was useing a cylider shaped magnet which is wider then it is tall, so it pretty short, and I was trying to drive the magnet with a H bridge useing four 2n2222 bipolar transistors and 5 volts. I was also have trouble getting and keeping the magnet intirely coiled in wire. Does anyone know what I'm doing wrong or have any tips?
Thanks for the help! (=
This is the schematic I used to make the circuit but I didn't use the 22k resistor it tell you to use, I used 1k resistors, 5V and I placed the permanent magnet coil where the DC motor should be in.View attachment 61511
