PPT-Cosmological magnetic fields

Andrii Neronov University of Geneva Durrer amp AN AampARev 21 62 2013 Overview Magnetic fields in astronomy and cosmology Characterization of cosmological magnetic fields Generation. Grav ity and magnetic exploration can help locate faults mineral or petroleum resources and groundwater res ervoirs Potentialfield surveys are relatively inexpen sive and can quickly cover large areas of ground What is gravity Gravitation is the for 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 Sunspot magnetic fields fields What are Sunspots?

We see versions of the argument in the work of both Plato and Aristotle.. There, of course, the argument was not aimed at proving the existence of a theistic divinity, but at explaining the origin of the world.. Magnetic fields and nomenclature. Lorentz force: . .
