    Notes: [Auszug] SIB,-The difference between Stopes-Roe (Nature, 228, 193; 1970) and myself (Nature, 227, 935; 1970) is less a question of fact than of what we consider has fundamental importance. We agree that the influence of a surrounding medium on the field of a magnet depends on the shape of that magnet. We ...

    Notes: [Auszug] In SI units the constant ^.0 = 47rx 10~7 is indispensable in many formulae, if the dimensions are to balance and the correct numerical values are to be obtained. The difficulty arises from attributing to this constant the physical properties of permeability. As shown by Stopes-Roe, different ...

    Production of Anisotropy in a Permanent Magnet by Pressure (1955)
    [s.l.] : Nature Publishing Group

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Since a large magnetostriction appeared necessary, 35 per cent cobalt steel was chosen for the experiment. The magnetostriction is positive, and in consequence a longitudinal tension or a lateral pressure will favour a square loop. A lateral pressure was obtained in a bar of cobalt steel about 1 ...

    ‘Spoiling’ of Tungsten Steel (1947)

    Notes: [Auszug] IT is known that the coercive force of tungsten magnet steel is reduced if the steel is maintained for a period at a temperature of 950–1,000°C. prior to hardening. The steel is then said to be ‘spoiled’. In some such samples of tungsten steel the compound WC has been detected, and it has been ...

    Notes: [Auszug] A reduction of 825 gauss in the reman-ence of a bar of 'Alcomax II' hardened without a field has been produced by a longitudinal pressure of 2-2 X 109 dynes cm.'2, suggesting that the increase in remanence of, say, 2,500 gauss produced by magnetic hardening would require a stress of 6 X 109 dynes ...
