PPT-Solar magnetic fields:

basic concepts and magnetic topology Anna Ania Malanushenko Plasma Is matter Mass is conserved Momentum is conserved Energy is conserved ionized and in magnetic field Obeys Maxwells equations. In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir .
