[0002] In modern teaching, electromagnetic induction is a crucial concept in physics, significantly contributing to students' understanding of the fundamental principles of electromagnetism. Traditional teaching devices for electromagnetic induction are typically simple in structure and single in function, primarily demonstrating the phenomenon through basic experiments, such as generating induced current through the relative motion of a coil and a magnet. However, these traditional devices have limitations. For example, they require an external power source, the experimental phenomena are not visually intuitive, and they struggle to engage students. Furthermore, traditional devices usually only demonstrate a single electromagnetic induction phenomenon, failing to comprehensively showcase multiple related physical phenomena, such as electromagnetic drive and the thermal effects of eddy currents. This restricts students' comprehensive understanding and in-depth learning of electromagnetism. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-4 As shown, this utility model is a multi-simulation combined teaching device, including a base plate 1;

[0027] The substrate 1 is fixedly connected to a first support rod 2 and a second support rod 3. The upper end of the first support rod 2 is rotatably connected to a slotted plate 4. The bottom wall of the slotted plate 4 is fixedly connected with several strong magnet blocks 5 at equal intervals and in a circumferential array. A transparent plastic plate 6 is fixedly connected to the slotted plate 4. The upper end of the second support rod 3 is rotatably connected to a connecting plate 7. A disc 8 is fixedly connected to the upper wall of the transparent plastic plate 6. A transmission belt 9 is sleeved on the outer wall of the disc 8 and the connecting plate 7.

[0028] Induction-generated power generation components;

[0029] Electromagnetic drive components;

[0030] Thermal effect components.

[0031] As can be seen from the above, when in use, the operator rotates the connecting plate 7, and takes advantage of the characteristics of the disc 8 and the transmission belt 9 sleeved on the outer wall of the connecting plate 7, which in turn drives the disc 8 to rotate, further driving the slotted plate 4 and several strong magnet blocks 5 to rotate. Moreover, through the set induction power generation component, electromagnetic drive component and thermal effect component, it is convenient for personnel to understand and learn about electromagnetic induction knowledge, and the structural design is user-friendly.

[0032] Depend on Figure 1 It can be seen that there are sixteen strong magnet blocks 5.

[0033] Specifically, each of the strong magnet blocks 5 is made of four neodymium magnets stacked together, and a total of sixteen strong magnet blocks 5 are provided to enhance the magnetic field strength.

[0034] Depend on Figure 1 It can be seen that a handle 10 is fixedly connected to the upper wall of the connecting plate 7.

[0035] Specifically, the operator can rotate the connecting plate 7 by holding the handle 10, making the operation convenient.

[0036] Depend on Figure 1 and Figure 3 It is understood that the inductive power generation component includes a base plate 11 and a mounting plate 12 fixedly disposed on the upper wall of the base plate 11. A mounting slot is provided on one side wall of the mounting plate 12, and an LED bead 13 is fixedly installed inside the mounting slot. A support column 14 is provided on one side of the base plate 11, and an electromagnetic coil 15 is fixedly installed on the upper end of the support column 14. A first connecting wire and a second connecting wire are connected to the electromagnetic coil 15. The first connecting wire is connected to the positive terminal of the LED bead 13, and the second connecting wire is connected to the negative terminal of the LED bead 13.

[0037] Specifically, the number of LED beads 13 can be set to multiple, so that personnel can observe the on and off states of the LED beads 13;

[0038] As can be seen from the above, when the tray 4 and several strong magnet blocks 5 are rotating, the operator can bring the electromagnetic coil 15 close to the tray 4. Due to the principle of induction charging, the LED beads 13 will light up, and the operator can directly observe the phenomenon of induction charging.

[0039] Depend on Figure 2 and Figure 4 It is known that the thermal effect component includes a base 16 and a positioning rod 17 fixedly disposed on the upper wall of the base 16. A guide U-shaped plate 18 is movably disposed on the outer wall of the positioning rod 17. An aluminum sheet 19 is placed on the inner bottom wall of the guide U-shaped plate 18. A temperature sensor 20 is fixedly connected to the aluminum sheet 19. A temperature display 21 is disposed on the base 16. The temperature sensor 20 is electrically connected to the temperature display 21.

[0040] As can be seen from the above, when the tray 4 and several strong magnet blocks 5 are rotating, the operator will gradually bring the aluminum sheet 19 with temperature sensor 20 close to the tray 4. The temperature sensor 20 senses the temperature and further displays the temperature value through the set temperature display 21, so that the thermal effect of the eddy current can be observed intuitively.

[0041] Depend on Figure 4It is known that a first screw 22 is movably connected through the upper wall of the guide U-shaped plate 18, and a first knob is fixedly connected to the upper end of the first screw 22. A second screw 23 is movably connected through one side wall of the guide U-shaped plate 18, and a second knob is fixedly connected to one end of the second screw 23.

[0042] As can be seen from the above, the position of the guide U-shaped plate 18 can be fixed by rotating the second screw 23. At this time, one end of the second screw 23 abuts against the outer wall of the positioning rod 17.

[0043] The position of the aluminum sheet 19 can be further fixed by rotating the first screw 22, at which time the lower end of the first screw 22 abuts against the upper wall of the aluminum sheet 19.

[0044] Depend on Figure 2 It is known that the electromagnetic drive assembly includes a crossbar 24 fixedly installed on the upper outer wall of the positioning rod 17. The outer wall of the crossbar 24 has a through hole, and a guide rod 25 is rotatably connected inside the through hole. An action rod 26 is fixedly connected to the lower end of the guide rod 25. Two aluminum plates 27 are symmetrically and fixedly connected to the lower outer wall of the action rod 26.

[0045] A small windmill can be fixedly installed at the upper end of the guide rod 25;

[0046] As can be seen from the above, when the person brings the rod 26 with the aluminum plate 27 close to the tray 4, the windmill will slowly accelerate its rotation, and the electromagnetic drive phenomenon can be directly observed, which has educational significance.
