Magnetical Investigations [Paperback]

Published 183952, this is a pioneering two-volume work on magnetic science by whaler and scientist William Scoresby (17891857).Published 183952, this two-volume work records the contribution of William Scoresby (17891857) to magnetic science, a field he considered one of 'grandeur'. The result of laborious investigations into magnetism and (with James Prescott Joule) electromagnetism, Scoresby's work was particularly concerned with improving the accuracy of ships' compasses.Published 183952, this two-volume work records the contribution of William Scoresby (17891857) to magnetic science, a field he considered one of 'grandeur'.

The result of laborious investigations into magnetism and (with James Prescott Joule) electromagnetism, Scoresby's work was particularly concerned with improving the accuracy of ships' compasses. A whaler, scientist and clergyman, he epitomised the contribution which could be made to exploration and science by provincial merchant mariners  men often less celebrated than their counterparts in the Royal Navy or in metropolitan learned societies. In addition to his pioneering work on magnetic science, Scoresby furthered knowledge of Arctic meteorology, oceanography and geography. Volume 1 considers the magnetism of steel and suggests ways to determine its quality and hardness.Part I: 1. Introductory observations; 2. Description of ready and effective processes for magnetizing large bars and thin plates; 3. The ready determination of the proportional directive powers of magnetic needles or bars; 4. The determination of the relative strength or tenaciousness of the magnetic condil“m
