Details:
We’ve all seen the outline of a magnetic field in two dimension by placing magnets under a piece of white poster board with iron shavings or flakes on top. But we can only see the out-lines of the magnetic field. I wanted to see it in three dimensions. So I took a magnet and fetched some magnetite from the dirt in my front yard. My plan was to take a pudding cup and place a magnet at the bottom, filling the cup with clear resin. After the resin began to heat up, I started sprinkling the magnetite on top. The hope was that the magnetite would fall along the magnet lines. Instead the resin was too thick and the magnetite only floated on top. So I poured all the magnetite that I had collected to see if the floating structure would sink. It sure did! The floating magnetite structure appeared it was all going to sink to the bottom around the magnet, being a complete failure. Suddenly the resin began to harden at the perfect time. What the resin had captured was amazing. The structures that are suspended above the magnet look very familiar to the prominences we see on the sun. There is even an empty canal space void of any magnetite along the center of the magnet from pole-to-pole with a canopy above it. I added orange and yellow to the photo to give the magnetic structures an appearance as we see on the sun. How cool is that, a magnetite prominence frozen in time!
