  • Can you remember the qualitative properties of the magnetic phenomena that you studied in previous years?

  • Do you understand the effects of the magnetic fields on charged particles and currents? Can you explain some of the practical uses of these forces?

  • Can you measure the magnetic field under simple conditions? Do you understand the phenomenon of natural magnetism?

  • Do you know what magnetic induction is? Can you explain how it can be applied to the production of alternating current? Could you describe some of the main properties of alternating current?

    You can test your knowledge with the following three tests:
