magnetic field energy density is given by
total volume of mass released=mass/density=3.333*10^18 m^3
total energy=0.5 *B^2*volume/uo=0.5*m*v^2
solving this we get B=11.64 T
Magnetic fields at the surface of the sun can be strong enough to cause solar material...
Problem 30.45 Magnetic fields within a sunspot can be as strong as 0.4 T. (By comparison, the earth's magnetic field is about 1/10,000 as strong.) Large sunspots can be as much as 25,000 km in radius. The material in a sunspot has a density of about 3 x 10 kg/m3 Part A If 100% of the magnetic field energy stored in a sunspot could be used to eject the sunspot's material away from the sun's surface, at what speed would...
