Sun's magnetic field too small to be measured by direct effects on earth; measured by

Zeeman effect on spectrum lines.

Earth's magnetic axis inclined 12" to rotation axis.

Earth's field rotates at same speed as nearly rigid earth.

Earth : Polar intensity of field j gauss.

Sun : Intense local fields frequent, 3000 gauss. The magnetic field of spots reverses each

cycle (Proc. Astron SOC.Pacific, vol. 41, p. 136, 1929). The polarity of leading spot in a

bipolar group in the Northern Hemisphere is opposite that in the Southern Hemisphererelationship reverses each new sunspot cycle . complete magnetic cycle is double sunspot cycle.

Faraday discovered that, when a piece of heavy glass is placed in magnetic

field and a beam of plane polarized light passed through it in a direction parallel

to the lines of magnetic force, the plane of polarization of the beam is rotated.

This was subsequently found to be the case with a large number of substances,

but the amount of the rotation was found to depend on the kind of matter and

its physical condition, and on the strength of the magnetic field and the wavelength of the polarized light. Verdet’s experiments agree fairly well with the

formula



where c is a constant depending on the substance used, 1 the length of the path

through the substance, H the intensity of the component of the magnetic field

in the direction of the path of the beam, r the index of refraction, and A the

wavelength of the light in air. If H be different, at different parts of the path,

1H is to be taken as the integral of the variation of magnetic potential between

the two ends of the medium. Calling this difference of potential v, we may

write 6 = Av, where A is constant for the same substance, kept under the

same physical conditions, when the one kind of light is used. The constant A

has been called “Verdet’s constant,’’ and a number of values of it are given in

Tables 514-517. For variation with temperature the following formula is

given by Bichat :

R = R, ( 1 - 0.00104t - 0.000014tZ),

which has been used to reduce some of the results given in the table to the

temperature corresponding to a given measured density. For change of wavelength the following approximate formula, given by Verdet and Becquerel,

may be used :



where p is index of refraction and A wavelength of light.

A large number of measurements of what has been called molecular rotation

have been made, particularly for organic substances. These numbers are not

given in the table, but numbers proportional to molecular rotation may be derived from Verdet’s constant by multiplying in the ratio of the molecular weight

to the density. The densities and chemical formulas are given in the table. In

the case of solutions, it has been usual to assume that the total rotation is simply

the algebraic sum of the rotations which would be given by the solvent and dissolved substance, or substances, separately ; and hence that determinations of

the rotary power of the solvent medium and of the solution enable the rotary

power of the dissolved substance to be calculated. Experiments by Quincke

and others do not support this view, as very different results are obtained from

different degrees of saturation and from different solvent media. No results

thus calculated have been given in the table, but the qualitative result, as to the

sign of the rotation produced by a salt, may be inferred from the table. For

example, if a solution of a salt in water gives Verdet’s constant less than 0.0130

at 20°C, Verdet’s constant for the salt is negative.

As a basis for calculation, Verdet’s constant for carbon disulfide and the

sodium line D has been taken as 0.0130 at 20°C.
