5. Let's suppose we want to create a magnetic field for an asteroid that does not have one. We can assume the asteroid is rocky, so it's not ferromagnetic. For a spherical asteroid of radius 26 meters and a magnetic field strength of 10^(-4) Tesla, how much energy do we need to create the magnetic field? You may assume the magnetic field is constant over the spherical asteroid and drops rapidly to zero outside. In case you need to look it up, the volume of a sphere is (4/3)*pi*r^3.

A particle’s path is bent when it passes through a region of non-zero magnetic field although its speed remains unchanged. This is very useful for “beam steering’’ in particle accelerators. Consider a proton of speed 4106m/s entering a region of uniform magnetic field 0.2 T over a 5-cm-wide region. Magnetic field is perpendicular to the velocity of the particle. By how much angle will the path of the proton be bent? (Hint: the particle comes out tangent to a circle.
