This once I will take pity.In very simple cut down terms, think capacitor with permanent charge, just like a permanent magnet.(in reality both are never really permanent)Often is a piece of dielectric plastic. Look up electret microphone for an eg of practical application.Next time pretend you are researching a subject.
Is the sun an elecret and produces an electrostatic polarised field opposed to matters magnetic fields?
