Magnetic fields

Interesting stuff on the magnetic fields. I recently did a video on an experiment that I did not think belonged in this video that demonstrated how a weak magnetic force could be overwhelmed and completely redirected by the stronger magnetic force. This was a simple test involving a ceramic magnet and a neodymium magnet and a compass. I took two opposition poles and demonstrated that as the stronger magnet was pushed into the weaker magnet it would stick to the weaker magnet and the compass needle would spin in the opposite direction. Then when pulled apart the compass needle would redirect in the opposite direction again. Then I brought the stronger magnet still in opposition and demonstrated that even though the compass needle still pointed in the direction of the weaker pole the needle could be moved by moving the stronger magnet back and forth. This demonstrates that the magnetic forces are constantly being influenced by the stronger forces inside of the motor. When the battery is producing a current through the electromagnet the permanent magnet's field is being reshaped as the rotor spins through it. Once the electromagnet's field collapses the permanent magnet wants to reestablish it's field. This happens instantly. I think this push back is what gives the coil it's induction.
Looking forward to the next project. Good Success.
