Magnetic field distribution in the tail of Halley's Comet found from the kinematics of a plasma formation

The distribution of directions of magnetic field vectors along the trajectory is found from the accelerations of a plasma formation moving in the tail of Halley's Comet. The magnitude of the field in the comet's tail proves to be greatest at the boundary and declines sharply within the tail. This means that there is a magnetic barrier at the boundary of the tail. A map of the magnetic field in the tail of Halley's Comet is constructed which agrees well with a laboratory model of an induced magnetosphere.
