The Theory of Magnetic Variometers (Teoriya magnitnykh

ABSTRACT:
The article discusses the general theory of interaction of a
magnetic field with permanent magnets, resulting in the con-
struction of universal bi-filar variometers and magnetic balances.
A full mathematical treatment considers all the factors involved,
including the optical systems and the correction of errors and
irregularities. Of particular interest is a temperature-compensation
technique for variometers using a new alloy, called calmalloy
(or "kalmalloy"), in which a plate of Mi-Cu-Fe is superposed
directly on the magnet system. The permeability of the calmalloy
falls with the rising temperature and the plate develops the
compensatory setion of an armeture which, by closing the magnetic
flux, decreases the magnetic moment of the system. The calmalloy

plate was first used by B. M. Yanovskiy. Its main advantage over other
available systems is that it will compensate for changes in temperature
under any condition within the given temperature range. Furthermore,
the calmalloy plate, being placed directly above the magnet system, has a
smaller thermal inertia than that of the system of suspended magnets. In
the latter system the suspended magnets are kept at some distance from the
magnet of the variometer and thus differ from it in temperature. The
disadvantage of the use of the calmalloy plate as a compensating agent lies
in the differences in the composition of the alloy, i.e., the different
percentages of its three main ingredients (MI, Cu and Fe). Consequently,
the main drawback in the use of the instrument equipped with a calmalloy
plate is the need to adjust the instrument in advance, if the calmalloy plate
is to respond accurately to fluctuations in temperature. The adjustment is
done with a view to the range of temperature fluctuations in each particular
area where the variometer will be used; without these preliminary adjust-
ments the accuracy of the compensation would be distorted. After weighing
the pros and cons of the use of a calmalloy plate for temperature compensa-
tion, the conclusion is drawn that compensation by calmalloy is simpler

than compensation by suspended magnets. The author of the article sees
no value in the use of permalloy or perminvar for similar purposes.
V. N. Bobrov, a member of the staff of the Irkutsk magnetic observatory,
is mentioned. The article is accompanied by 22 drawings, 5 tables, and
11 references, of which 9 are Russian.

TITLE :
On the Structure of the Diurnal Course of Magnetic Activity
(O strukture sutochnogo khoda magnitnoy aktivnosti)
.
'PERIODICAL:
Doklady Akademii Nauk SSSR, 1958, Vol. 118, Nr 6,
pp. 1109-1112 (USSR)
ABSTRACT :
The present paper uses the 5-year-old data on the diurnal
course Sa of the magnetic activity of 34 observatories on
the northern and 7 observatories on the southern hemisphere.
The author investigates here the problem of the structure of
Sa and of the nature of its natural components. Here the
relation Sa = S' (t) + S"(T) is assumed, whereby t denotes the
local time and T = t + 7 the world time. The corpuscular
currents which cause the magnetic disturbances move first
according to the laws of the theory of Chapman (Chepmen)-
-Ferraro, and then in the trajectories of Stormer (Shtermer).
A relation for the lower boundaries of the width of the zone
in which the particles are deposited is written down. First
it is shortly reported on a process for the determination of
Card 1/3
the semiannual component of the activity. As the harmonic
analysis shows, the differences Sa - S" are well determined
On the Structure of the Diurnal Course of Magnetic Activity
20-118-6-16/43
by the first term of the Fourier series, similar to S". The
initial phases Q of the first harmonics of the curves Sa -
- S" are illustrated in a further diagram. Then a formula for
tgy is written down. A further component exists with respect
to world time which is here denoted by S". The amplitudes
and the phases of the first harmonics S' (t) = S. - S" - S"
are illustrated here in a diagram. The data given here speak
in favor of the existence of two types of S'; the one (with a
maximum at approximatively noon) predominates near the
magnetic equator, and the second (with a maximum at approximat-
ively midnight) predominates near the zone of aurorae polaris.
The function S' can therefore be written down as follows: S' (t)-
= Roos(t-}) = a($)cos(t -a) + b(6)cos(t - 3). The authors
assumed here &= 0, which is confirmed by the data of different
seasons and the data of calm days. For the determination of the
values of 3 the author used the values concerning the daily
alterations of the sudden commencement sc of the magnetic
storm. The nature of the component S" is obviously determined
by the influence of the rotation of the magnetic axis on the
position of the traces of the main directions of incidence in
the atmosphere. There are 3 figures, 1 table, and 12 references,
5 of which are Soviet.

Soviets Claim the Only Nonmagnetic Ship in the World
A three-masted sail-motor schooner of 600 tons, specially constructed
almost entirely of wood, bronze, brass, and nonmagnetic steel (the last
material mainly in the motor and so far from the measuring instruments
that it exerts no influence) by the Scientific Research Institute of Ter-
restrial Magnetism, Ionosphere and Radio Wave Propagation, will conduct
magnetic measurements in the Baltic and Pacific during 1957 and 1958 in
connection with the IGY, according to N. Pushkov, chief of the institute. '
The Zarya, as the schooner is called, can travel 3,500 miles on its
stores of Diesel oil and water and is unique in being completely nonmag-
netic. (Moscow, Vodnyy Transport, 28 Jul 56)
