SUMMARY: Researchers have discovered that temporary cracks can form in the Earth's magnetic field that can permit some of the solar wind's energy to slip through and disrupt electronics and communications. These observations were made using NASA's Imager for Magnetopause to Aurora Global Exploration (IMAGE) satellite, which tracked a large aurora for several hours. The ESA's Cluster satellites flew over the same location and spotted a stream of ions slipping through a crack which normally should have been deflected by the Earth's magnetosphere.

The notion of "magnetic reconnection" is wrong it should be considered an electrical breakdown (short-circuit or lightning flash) of an electrical double layer. Maybe Earth's magnetic field is not created by the Earth but by it's surroundings, forming a double layer.
Cheers.
