Hello All, In Mathematica 5.2 and earlier I could create a Notebook like: << Graphics` $FormatType = TraditionalForm; $TextStyle = {FontFamily -> "Times", FontSize -> 12}; Strip = {Polygon[{{-0.1, 0, 1}, { 0.1, 0, 1}, {0.1, 0, 0} + s, {-0.1, 0, 0} + s}], Polygon[{{-0.1, 0, 0} + s, {-0.1, 0, -1}, {0.1, 0, -1}, {0.1, 0, 0} + s}]}; Magnet = {Cuboid[{-1, -0.5, -0.1}, {-0.2, 0.5, 0.1}], Cuboid[{0.2, -0.5, -0.1}, {1, 0.5, 0.1}]} Wire = {Line[{{0, 0, -1}, {0, 0, -1.2}, {-1.4, 0, -1.2}, {-1.4, 0, -0.2}}], Line[{{-1.2, 0, -0.2}, {-1.7, 0, -0.2}}], \ Line[{{-1.3, 0, 0}, {-1.6, 0, 0}}], Line[{{-1.4, 0, 0}, {-1.4, 0, 1}, {-0.1, 0, 1}}]}; circuit = Table[ Show[Graphics3D[{Magnet, Strip, Wire}], Epilog -> {Text["N", {.402, .504}], Text["S", {.62, \ .47}], Red, Arrow[{.53, .71}, {.53, .16}], Text["Current", {.7, 0.69 - .394t}]}, Boxed -> False, PlotRange -> {{-1.8, 1.5}, {-1, 1}, {-1.3, 1.3}}], {t, 0, 1, 0.05}]; Export["Conductor.gif", circuit, ConversionOptions -> {"Loop" -> True}] to create animations as in http://web.me.com/timbrophy/physicsnow/currentm.html In versions 6 and 7 the Table command does not produce all the files I need for the animated gifs. How can I do the same? Manipulate is no good as I simply want gifs to demonstrate different aspects of Physics to my students. Tim Brophy
