Frostorian #039- Energy

"Joseph Henry was a researcher in the field of electricity whose work inspired many inventors. Henry's first discovery was that the power of a magnet could be immensely strengthened by winding it with insulated wire. He was the first person to make a magnet that could lift 3,500 pounds of weight. Henry showed the difference between "quantity" magnets composed of short lengths of wire connected in parallel and excited by a few large cells, and "intensity" magnets wound with a single long wire and excited by a battery composed of cells in series. This was an original discovery, greatly increasing both the immediate usefulness of the magnet and its possibilities for future experiments."
