How does a speaker coil move if it can not feel its own magnetic field?

The coil in a speaker that's attached to the diaphragm moves as current passes through it thereby creating a magnetic field. Theres a permanent magnet nearby, but the coil somehow feels its own magnetic field that it generated to become either a north or south pole and be repelled or attracted by the permanent... show more The coil in a speaker that's attached to the diaphragm moves as current passes through it thereby creating a magnetic field. Theres a permanent magnet nearby, but the coil somehow feels its own magnetic field that it generated to become either a north or south pole and be repelled or attracted by the permanent magnet? How is that possible? How could a wire feel its own magnetic field??
Update: can you explain what you mean by the magnetic field on the coil interacts with the field from the permanent magnet?
Update 2: CwCC, so basically as the current changes direction, the force due to I cross B changes and that makes it move? B being the field from the permanent magnet?
