This is beacuse magnetism has been decided as the cause for electric fields, not the other way around. This makes magnetism an acceptable subject as long as one doesn't mention the currents needed to sustain such fields. This is why all of the talk about magnetic reconnection etc lately. They are going to bring in electric currents into thier cosmology as soon as they figure out how to claim it is caused by the magnetism. They know current cosmology is lost, but like stubborn children caught in the act they still deny it. They are afraid to look like the fools they are for holding on to a theory long dead, so are attemtpting to work it in slowly so no one will notice.
