... not described earlier in university settings. The model of the “overlapping magnetic fields” starts from the idea that not only a magnet but also a coil, even without a current, produces a magnetic field. In this model, when a magnet enters a coil, both fields start to overlap, creating one common field...

... Hassana et al. (2019) 0.001 3 431 0.2 0.22 Electromagnetic MEH The operating principle of electromagnetic MEH devices is based on Faraday's law, which states that a relative motion between a magnetic field and an electrical coil or a change in the flux linkage with a coil induces...

... parameters. Here, we take three passive electrical elements inductor, capacitor and resistance to determine the scaling effect. FIG. 2.8 Schematic of an inductor. Inductance Here, we consider N as the number of coils per unit length (see Fig. 2.8 ), with the length of the inductor as L...

.... They have a magnet, a coil, and a galvanometer. Their task is to find a way to induce a current in the coil so that the galvanometer shows a reading. By doing observational experiments, in this case trial and error, they first devised an idea that a magnet moving with respect to a coil in a specific way...

... springs were made from the same kind of wire, and the same number of coils, and that the only difference between them was the diameter of each spring, where one was twice the diameter of the other. The experts were asked to predict the relative length of each spring if the same weight was suspended...

Delving into compass-coil interactions, modeling and debating ideas, they discerned a circular relationship analogous to the “right hand rule” of decontextualized physics...

... current) it is necessary to move the magnet faster, use stronger magnet and use coil with more loops.” This statement could form the common misconception that if there is a voltage, there should be a current. This is not always correct. Another study by Yildiz (2015) focused on the expression “All...
