Description

Technical Field

[0001] The utility model relates to the technical field of physical experiments, in particular to an electromagnetic swing demonstration model of physical experiments. Background Art

[0002] In the teaching process, the teaching of "electricity and magnetism" is usually demonstrated using corresponding real objects. In this way, students can intuitively understand scientific principles such as "a coil with electricity can generate magnetism" and "a coil with electricity also has north and south poles", thus stimulating their interest in learning.

[0003] In the existing technology, the teaching method generally adopts the method of fixing a compass in the middle of a coil, and then connecting the coil with the fixed compass to a circuit, and by observing the direction of the compass, the students can understand the connection between electricity and magnetism. However, since the compass lacks interest and is crudely made, this method is not suitable for demonstration to primary school students. Utility Model Content

[0004] The utility model aims to solve the problem that the compass in the prior art lacks interest and is crudely made, and this method is not suitable for demonstration to primary school students, and proposes an electromagnetic swing demonstration model for physical experiments.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An electromagnetic swing demonstration model for a physical experiment comprises two plastic plates, on which a same fixed iron sheet is fixedly installed by bolts, a battery box is arranged on the top of the plastic plate, electric wires are installed on the battery box, a double-sided tape is fixed on the top of the plastic plate, and a magnet is adhered to the double-sided tape;

[0007] The plastic plate is provided with a swing-like swing structure for demonstration, and the swing structure is conductive and electrically connected to the wire;

[0008] The swing structure includes an installation iron sheet 1 fixedly installed on the top of the plastic plate by bolts, a heightening plate fixedly installed on the installation iron sheet 1 by bolts, an installation iron sheet 2 fixedly installed on the heightening plate by bolts, a connecting plate fixedly installed on the two installation iron sheets 2 by bolts, an L-shaped iron piece fixedly installed on the bottom of the connecting plate, the L-shaped iron piece is wound with copper wire, and a copper coil is wound on the bottom of the copper wire.

[0009] Preferably, the copper wires are arranged in pairs, and two of the copper wires are wound around the same copper coil.

[0010] Preferably, the electric wire and the copper wire are connected.

[0011] Preferably, the L-shaped iron piece is provided with a mounting hole for facilitating the winding of the copper wire.

[0012] Preferably, the copper coil is arranged directly above the magnet.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model sets a swing structure. When the copper coil with electricity generates a magnetic field, the magnetic field interacts with the magnetic field generated by the magnet, thereby driving the swing-like copper wire to swing. As the swing amplitude increases, the periodic changes of the back-and-forth swing can be observed more intuitively. This design not only increases the fun of the experiment, but also helps students better understand the effects of electromagnetic force and the periodic changes of physical phenomena.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 , an electromagnetic swing demonstration model for physical experiments, including two plastic plates 1, on which the same fixed iron sheet 2 is fixed by bolts, and the fixed iron sheet 2 ensures the stability of the entire structure. A battery box 3 is arranged on the top of the plastic plate 1, and the battery box 3 is used to provide electrical energy. An electric wire 4 is installed on the battery box 3, and the electric wire 4 transmits the electrical energy to subsequent components. A double-sided tape 5 is fixed on the top of the plastic plate 1, and a magnet 6 is adhered to the double-sided tape 5; this design enables the magnet 6 to be firmly fixed on the plastic plate 1, and at the same time, it is easy to adjust its position to meet different experimental needs.

[0021] A swing-like swinging structure for demonstration is arranged on the plastic plate 1 . The swinging structure is conductive and electrically connected to the electric wire 4 .

[0022] The swing structure includes an installation iron sheet 1 8 fixedly installed on the top of the plastic plate 1 by bolts, a heightening plate 9 fixedly installed on the installation iron sheet 1 8 by bolts, and an installation iron sheet 2 10 fixedly installed on the heightening plate 9 by bolts, and the bolt connection method ensures the stability and flexibility of the swing structure. The two installation iron sheets 2 10 are fixedly installed with a connecting plate 11 by bolts, and the connecting plate 11 further reinforces the entire swing structure. An L-shaped iron piece 12 is fixedly installed at the bottom of the connecting plate 11, and the L-shaped iron piece 12 is wrapped with a copper wire 13, and a copper coil 7 is wrapped at the bottom of the copper wire 13. The design of the copper coil 7 enables the copper wire 13 and the copper coil 7 to form a complete electromagnetic circuit. When current passes through, a magnetic field is generated, thereby driving the swing structure to swing.

[0023] The copper wires 13 are arranged in pairs, and two copper wires 13 are wound around the same copper coil 7. This design not only increases the effect of the electromagnetic force, but also improves the demonstration effect of the entire model.

[0024] The electric wire 4 is connected to the copper wire 13. This design ensures that the electric energy can be smoothly transmitted to the copper wire 13 and the copper coil 7.

[0025] The L-shaped iron piece 12 is provided with a mounting hole 14 for winding the copper wire 13. The design of the mounting hole 14 makes the installation and replacement of the copper wire 13 simple and quick.

[0026] The copper coil 7 is arranged just above the magnet 6. Under the effect of this design, when the electromagnetic force acts on the copper coil 7, a swing-like swinging effect can be simulated.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] Two plastic plates 1 are fixed with bolts to ensure the stability of the entire structure. A battery box 3 is set on the top of the plastic plate 1, and a wire 4 is installed to provide electrical energy and transmit the electrical energy to subsequent components. A magnet 6 is adhered to the double-sided tape 5 so that its position can be adjusted to meet different experimental needs.

[0029] The installation iron sheet 1 8, the heightening plate 9, the installation iron sheet 2 10 and the connecting plate 11 are fixedly installed by screwing bolts to further strengthen the entire swing structure. Copper wire 13 is wound on the L-shaped iron piece 12, and copper coil 7 is wound on the bottom of copper wire 13, and the electric wire 4 and copper wire 13 are connected to ensure that electric energy can be smoothly transmitted to copper wire 13 and copper coil 7. Using the installation hole 14 opened on the L-shaped iron piece 12, the copper wire 13 is wound on the L-shaped iron piece 12 to form a complete electromagnetic circuit.

[0030] When current passes through the copper wire 13 and the copper coil 7, a magnetic field is generated, thereby driving the swing structure to swing. Since the copper coil 7 is arranged directly above the magnet 6, when the electromagnetic force acts on the copper coil 7, a swing-like swing effect can be simulated.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
