Elements of the Mathematical theory of electricity and magnetism
... of a circle of radius 2ir traversed by unit current. Thus- knowing the unit current
we can at once determine the unit magnetic force. Having got the unit magnetic
force, the unit magnetic pole follows at once, since it is the pole which is acted ...

... on a magnetic pole at any point being called the intensity, of Me field. Hence
the intensity of the field at any point is measured by the force with which it acts on
a unit magnetic pole placed at that point. In absolute measurqtherefore, the unit
of ...

According to work law, the work done in moving a unit magnetic pole once
around the magnetic circuit (i.e. path ABCDA in this case) is equal to the ampere-
turns ...
V. K. Mehta, Rohit Mehta, 2008
In this connection we define a unit magnetic pole as one which when situated 1
metre distant in vacuum from an equal pole experiences a force of u.0/4n
newtons. Alternatively it can be defined as that pole strength which when placed
in a unit ...

The Mathematical Theory of Electricity and Magnestism
The Unit Magnetic Pole. 401. Just as Coulomb's electrostatic law of force
supplied a convenient way of measuring the strength of an electric charge, so the
law expressed by equation (328) provides a convenient way of measuring the
strength ...

From Obscurity to Enigma: The Work of Oliver Heaviside, ...
Recalling that the magnetic force acts along the arc, the work done against it per
unit magnetic pole in covering that distance is simply BrdQ . In other words,
substituting the magnitude of B from the first case of eq. (3-1), the energy required
to ...

Then m =1 or m = ± 1 weber* Hence, a unit magnetic pole may be defined as (hat
poie which when placed in vacuum at a distance of one metre from a similar and
equal pole repels it with a force of l/4n ^ newtons-** 6.3. Magnetic Field ...

This equation is used to define what is meant by a unit magnetic pole. In the cgs (
centime ter-gram-second) system, the constant na is arbitrarily taken to be one in
a vacuum. A unit magnetic pole in this system is now defined as one which ...

The " intensity of the field " at any point is measured by the force with which it acts
on a unit magnetic pole placed at that point. Hence, unit intensity of field is that
intensity of field which acts on a unit pole with a force of one dyne. There is ...

Basic Radiological Physics
Since a unit magnetic pole does not exist, this definition is of no use in
determining the intensity of the magnetic field. Hence, the concept of magnetic
field is modified as follows. The force experienced by a moving electric charge in
a magnetic ...
