1. THE MAGNETIC FIELD
A magnetic field is manifested by a force affecting certain materials in its environment,
acting on moving electrical charges. The magnitude of this force decreases as a function
of the distance between the magnetic field emitter and its action point. Magnetization
is a vector quantity which characterizes on a macroscopic scale the magnetic behaviour
of a material sample. It is measured in amperes per metre (A/m) or in Tesla (T). (1)
Ferromagnetism designates the ability of certain material samples to become magnetised
under the effect of an external magnetic field, and to retain part of this magnetisation.
On a microscopic scale, a ferromagnetic material can be described as a set of independent
magnetic domains (Weiss domains).
When the magnetic moments of the domains are not aligned, the total magnetostatics
energy of the material is minimised: the material is not magnetised.
(2)
For demagnetization purposes, a damped magnetic excitation field is applied so
that certain domains are reversed more than others, depending on the magnetic
excitation force passing through them. This leads to a state of magnetic disorder
equivalent to the state of a non-magnetized material. (3 and 4)
There are relatively intense magnetic fields all around us in daily life. It goes without saying that mechanical watches are
influenced by them, and thereby undergo potentially significant operating variations, i.e. which affect the rate precision.
It should be noted that the Earth’s magnetic field varies between 25 and 65 μT, depending on geographic position.
The most significant items in everyday life which can affect the rate of a mechanical watch by means of a magnetism effect
are computers, mobile phones, TVs, refrigerators, etc. Magnetic flux measurements (taken at 10 cm from the source) have
revealed values of 60 μT for an electric toothbrush, 75 μT for a mobile phone and 110 μT for a computer. Consider too that
watchmaking tools often have a magnetic charge capable of disrupting the rate of a watch !
The distance at which a watch is placed from the magnetising object is an important factor. Although watch manufacturers
regularly equip their cases with protective materials or opt for non-magnetic components, nevertheless rate problems due
to magnetism remain very common.

3. HOW TO INTERPRET THE MAGNETIC FIELD WITH THIS DEVICE
4. OPERATION
The HOROTEC© MAGTEST is an electronic device for the detection of magnetism in μTesla (μT), demagnetization and control
of magnetic remanence of watches, movements, tools and watch parts.
It combines the measurement function with the demagnetization function in a single device.
After demagnetization, the residual magnetism value in μT can be checked again.
A. Detection of the degree of magnetism in μTesla with display of the magnetic remanence. DETECT
B. Demagnetization cycle.
DEMAG
Large metal parts, such as a movement, modify the lines of the earth’s magnetic field. For this reason, an indicative value
of up to 50 μT can be considered without any influence or consequence on the functioning of the movement.
For small parts, such as screws, the displayed values must be considered as real remanence values.

10. SWITCHING ON THE DEVICE
Press the ON/OFF button located at the rear panel of the device to turn it on.
The following screen displays :
To check the degree of magnetism of small parts (screws for example), it is recommended to
place them in the white areas of the example shown here. The sensor placed in the centre and
the two zones between the 3 outer circles (in red) will not detect the degree of magnetism
of the small parts.
The search for magnetic remanence is active.
If the displayed value is greater than «0 μT», it is recommended to reset the sensors. see paragraph 10D4
A2. Sensors
There are 5 sensors and one of them is located in the centre of the detection surface. The others are in the corners of a 1.5
cm square. They can measure the magnetism force as well as the position. A dot on the LCD screen shows a sensor with its
position and the dot size is proportional to the magnetic force.

A. Magnetism detection
1. Press the DETECT key on the main menu MAGTEST to check the degree of magnetization of the object (watch,
movement or any other watch piece).
The following screen displays :
DETECT
0 µT DEMAG

Place the object to be tested on the DETECT ZONE surface.
- If the screen remains neutral (as in the image above), it means that the object placed on the detection surface is not
magnetized
- If red dots appear on the screen and a positive value in μT (as shown in the image below), it means that the object placed
on the detection surface is magnetized.
A3. In case of magnetic remanence
The following screen displays :
In case of magnetic remanence, the value displayed in μT, is the difference between the value of the Earth’s magnetic field
and the magnetism of the object being tested.
In addition to the value displayed in μT, red dots (up to 5) appear on the display indicating :
- By their presence, the magnetization surface
- By their size (diameter of the red dot more or less large), the importance of magnetism between the various sensors.
The value displayed in μT, will always be the highest value detected by the 5 sensors.
Place the object on the DEMAG ZONE surface and press the key
DEMAG
to demagnetize the object.
If the screen displays the presence of magnetism without any object on the detection surface DETECT ZONE, it is recommended
to reset the sensors. + see paragraph 10D4
Information :
In automatic mode, the device switches directly from DETECT mode to DEMAG mode.
Once the detection is complete (screen with red dots), remove the object from the DETECT ZONE surface. The device au-
tomatically switches to DEMAG mode. Place the object on the DEMAG ZONE surface and press the DEMAG button to start
demagnetizing the object.
