Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A magnetic structure, see fig. 1, wherein a housing (1) is a square body, and the upper half part of the housing is dark-colored coating (2) representing the south pole or the north pole of the magnet in the housing; the lower half of the casing is light-colored (3) representing the north or south pole of the magnet in the casing. An exploded view of the magnetic structure is shown in fig. 2, a cylindrical magnet (4) is embedded in the magnetic structure; meanwhile, correspondingly, the inner sides of the upper part and the lower part of the shell are provided with grooves (5) which can clamp the magnets. After the magnet is clamped in the groove of the shell, the magnet is fixed through industrial glue; the inside of the shell and the part outside the magnet are solid, so that the magnet can be firmly fixed in the shell, and the situation of looseness cannot occur.

It is understood that the housing may have other geometric shapes such as square, cylindrical or spherical shapes, and the magnets inside the housing may have other geometric shapes such as square, cylindrical or spherical shapes, as shown in fig. 3 and 4, so that they can be combined with each other and used.

Preferably, the shell is made of a plastic shell, so that the whole magnetic structure is lighter and more convenient for students to use; meanwhile, the shell is coated with an electroplated layer or a resin coating material with colors, so that the environment is protected, and the long-time playing is not influenced. As an alternative to a plastic housing, the housing may also be made of rubber, stone or other synthetic materials.

In order to facilitate edutainment, the two colors on the surface of the shell can adopt bright contrasting colors, and characters or patterns representing south poles and north poles of the magnets can be marked on the surface of the shell, so that a player or a user can clearly see the south and north poles of the magnets, and understand the physical phenomena that like poles attract each other and opposite poles repel each other.

Further, in an embodiment, the wall thickness of the housing is set to a predetermined thickness in accordance with the magnetic axial direction of the magnet, and the predetermined thickness is used to adjust the attraction force of the magnet in the magnetic axial direction. As shown in fig. 5, wherein the axial direction X represents the magnetic force direction of the magnet (4) at its south (S) or north (N) pole; the axial direction Y represents the magnetic force direction of the side surface of the magnet (4); the wall thickness (d) of the housing is the distance between the magnet (4) and the surface of the housing (1).

Because the magnetism of the magnet is strongest at two ends of the polarity of the magnet and weakest at the side surface of the magnet, namely the attraction strength in the axial direction X is greater than that in the axial direction Y, the wall thickness of the shell can influence the attraction strength of the magnet, namely when the wall thickness of the shell is larger, the attraction strength of the magnet in the direction is smaller; therefore, based on the principle, the wall thickness between the magnet and the surface of the shell can be adjusted, so that the attraction force of the magnet in different magnetic axial directions can be adjusted, for example, the attraction force in all directions outside the shell is uniform, and the purposes of slowing down the contact impact during mutual attraction, avoiding the shell from being broken due to impact and reducing the risk of pinching are achieved.

Specifically, as shown in fig. 6, if the attraction force between the two magnetic structures is F, and the distance between the center points of the two magnets is P, F is k/P²The suction relation of (1). K is the attraction constant of the magnet, and the maximum attraction is Fmax ═ K/(P-D) when the two magnets are attached and adsorbed²The distance of D is adjusted by the thickness of the shell, and a designed attaching attraction value can be obtained.

Further, by using the magnetic attraction force of a single magnetic structure, several magnetic structures can be freely combined into a magnetic structure combination as shown in fig. 7 like building blocks. The magnetic structure combination body can be combined into a cube, a strip or other geometric forms and applied to magnetic physical games or teaching experiments; therefore, the attractive north-south pole relation between every two magnetic blocks can be clearly seen.

It is right above the utility model discloses magnetic structure has been elucidated for help understand the utility model discloses, nevertheless the utility model discloses an embodiment does not receive the restriction of above-mentioned embodiment, and any does not deviate from the utility model discloses change, modification, substitution, combination, simplification made under the principle all should be equivalent replacement mode, all contain within the protection scope of the utility model.
