lol tim 118 is still a good mark...even at our school (this is adrian's brother btw). Aren't you like the maths gun in your grade? I don't think anybody in my grade is gonna beat you (maybe one or two?). I think I got 118 as well...lost 2(or maybe even 3 if the markers are tightass) from some...

I don't think Lenz's law is a good way to explain magnetic levitation. If a magnet is placed on top of a superconductor which is then lowered to its critical temperature it will levitate. There has been no relative change in flux to induce eddy currents in this case as the magnet was sitting...
