"A magnet is like a glass and the magnetism is like water. There's no way of getting a glass of water extra full. Full is full. Guys who play around with this will claim they get the rotor stronger, but it only lasts until the magnet is actually run. As soon as you run it you're right back to where you started. Think of your really full glass of water. As soon as you try to pick it up and move it some spills out, the rotor is the same way as soon as it is run you lose a little. Then it will stay consistent at that level until you get it hotter or expose it to a stronger field. "
