Title
[MBN006163], Technical Note, Charles Batchelor, October 4th, 1883
Editor's Notes
1000 light machine. Design specs. Interesting notes on magnetic induction in iron wires; a thought experiment methodically analyzed. p. 166 interested in legnth of magnets: "the length of a straight magnet does matter only with the action of one pole or the other. And if we use an horse shoe magnet, without any polarity in A [sketch], we may increase the height as much as we like." p. 169 then back to dynamos: speeds of new machines (table). Test to be made---proportions of magnet cores: "Object of experiment is to see if we get the same magnetism or if less what it is proportional to." p. 171; some tests on 300 and 150 light machines---changing weight and diameter of cores. p. 175 "Deductions: Increase section iron 1/2 keeping same weight & put on same number turns of wire and your magnetism is doubled." Other conculsions for other permutations. p. 177: "500 light redesigned" specs and some diags. [dynamo]
