but i will go with hard drives. if you have to break the operation of a magnetic hard drive down to a very basic level, it starts with magnetic domains. a magnetic domain is a region in the hard disk has a uniform magnetization. if you think of an atom as a tiny magnet, in each...
You'll want to get a strong magnet, probably neodymium (you can find a very strong magnet inside most computer hard drives, so if you have an old one kicking around that's a good source). Then, start attaching different ferrous or metal items to the sculpture. It's good to start on...
1971 and 1972: The Apollo Lunar Rover, the first electric car in space, drives across the Moon. Although not a hub motor vehicle, it popularizes the idea of vehicles whose four wheels are driven by independent motors. 1980s: Robert Lordo of Powertron is granted US Patent 4,453,097: Per...
