In addition, employees of the General Physics Department also closely cooperate with the Lviv Regional Small Academy of Sciences and contribute to the education of the future generation of qualified physicists. From September 2022 until now pupils are studying the course “Electricity and magnetism” in depth with great interest, passing laboratory work, where theoretical material is readily explained to them, and they have assistance in conducting an experiment and calculating the relevant quantities based on the obtained results.

In the process of learning, pupils performed 8 laboratory works under the guidance of assistant I. A. Pryshko:

  • Electrical measurements and measurement methods;
  • Study of Ohm’s law and Kirchhoff’s rules;
  • Electrostatic field study;
  • Study of the horizontal component of the intensity of the Earth’s magnetic field;
  • Study of the Hall effect;
