• Abstract:           The study of magnetism is one of the physical effects that is most charming to people who do not know the laws of physics, especially magnetism, and can be taken to other phenomena such as magic, mystery or the supernatural. In secondary schools, usually in the third year, students are studied and experimented:the story of how the properties of magnetite, magnets, poles: magnetic and geographic were discovered. In addition to induction lines, magnetic field, magnetization processes. The main part of this work is the demonstration of the magnetic field through the experiment with two tubes made of different materials placed vertically that have a super magnet, composed of neodymium, released simultaneously and subject to the magnetic field inside the tube and its fall time until the different soil. In order to demonstrate that phenomena like this cause enchantment in people, a questionnaire was developed and the distance between the action of the magnetic field and the knowledge of the interviewee's education was statistically and quantitatively analyzed. Send messages via social networks to various contact groups of the authors of this work, totaling twenty-five interviewees.
