Automated laboratory setup for remote spectral plasma diagnostics via the Internet // Mat. . "FNTP-2001. Petrozavodsk, 2001. V.2. S.13-17). The automated laboratory setup contains the studied radiation source, a condenser, a monochromator with a diffraction grating, a photoelectronic multiplier for receiving radiation and amplifying the signal in a narrow spectral range, and also an actuating element - a step motor for turning the grating to a position corresponding to the studied spectral range. There are also specialized power supplies for the emitter and photomultiplier tube.

The disadvantage of this setup is the inability to use it to calculate the magnetic fields of various objects.

This setup consists of a rectilinear conductor, a circular coil, a solenoid, a flat Hall sensor, a parallel reiter combined with a micrometer screw (positioning device), and an oscilloscope.

The disadvantages of this laboratory setup are the lack of automation and remote access.

The objective of the utility model is to create a laboratory setup for studying the magnetic fields of various objects, to provide educational experiments in the remote access mode to the laboratory setup, and to automate educational experiments.

The technical result is the automation of educational experiments and providing remote access to the laboratory setup.

The technical result is achieved by the fact that the laboratory installation for studying the magnetic fields of various objects contains: the object of study is a straight-line conductor, a circular coil, a solenoid, a device for measuring magnetic field strength based on a Hall sensor, a parallel router combined with a positioning device, an ATMEGA16 microcontroller, for automated local and automated remote control of the installation, connected through the interface unit to the computer and for control Lenia positioning device designed as a stepping motor, and to process the results obtained with the measuring device a magnetic field strength of the research object imaging device as a liquid crystal display, further set the local automated plant control keys.

The ATMEGA16 microcontroller, connected via a computer interface unit, allows you to automatically receive data from a laboratory setup using a predefined program. Local control of the installation is carried out using the control keys. Remote control of the laboratory setup is also carried out using an external computer through the interface unit. The information received from the computer is processed by the microcontroller, arriving at the positioning device, allows you to measure the magnetic field at a given point.

Thus, the set of essential features set forth in the formula of the utility model, allows to achieve the desired technical result.
