Magnetic field source and magnetic line stereoscopic display device

The invention relates to a magnetic field source and magnetic line stereoscopic display device, in particular, the iron particle dispersed in the suspended liquid is arranged and suspended in the suspended liquid from the magnetic field lines generated by the individual magnetic field source, thereby showing The position of the magnetic field source in space and the three-dimensional shape of the magnetic lines of force.

The magnetic lines of force generated by the magnet in space are only virtual lines that are easy to understand the characteristics of the magnetic field. The tangential direction of the magnetic lines of force represents the direction of the magnetic field, and the closeness of the magnetic lines of force can indicate the strength of the magnetic field.

In the conventional technique, the fine iron powder is dispersed on a non-magnetic carrier disk, such as a glass disk or a plastic disk, and when the magnet or the magnetic field source is gradually approached from below the carrier disk, the iron powder generates a magnetic force due to the magnetic field of the magnet.

In addition, when the magnet moves, the iron powder can be rearranged as the magnetic lines of force change, which is quite convenient to use, and the required materials are easily obtained.

However, the above-mentioned conventional technique has a drawback in that the fine iron powder dispersed on the carrier tray is easily loosened when the magnet is removed, and when the carrier tray is tilted, it slides down and is scattered, which is inconvenient to control, and collects iron again. Powder is quite laborious and time consuming. Furthermore, the fine iron powder on the carrier plate can only display the shape of the magnetic field lines on the plane, and cannot display the three-dimensional shape of the magnetic lines of force in the space, so it can only be understood by imagination. Although the computer can display the three-dimensional shape of the magnetic lines of force, the display can only display the shape of the magnetic lines of force generated by the specific magnet or the ferromagnetic coil. The user can not immediately move the magnet according to the desired movement and immediately observe the magnetic line. Variety.

The iron granules are made of a ferrous material suitable for general use, and if they are made of nano-iron powder, they are suitable for measurement of weak magnetic fields. In addition, the iron granules are suspended by the liquid, so that the granules are scattered and distributed in the suspended liquid without the influence of the external magnetic field or when there is no external magnet. If the magnet is close to the magnetic line stereoscopic display device of the present invention, the iron particles in the carrying container can be arranged along the magnetic lines of force generated by the magnet and suspended in the suspended liquid, so that the position of the magnetic field source and the magnetic field source can be immediately displayed. The three-dimensional distribution of the magnetic lines of force.

The above-mentioned carrier container is a rectangular parallelepiped, a cube or a cylinder made of a light transmissive material, such as a translucent glass or a translucent resin. The iron granules may be nano-powders, and the suspending liquid is an aqueous solution or an oily non-combustible liquid and is highly transparent.

In addition, the carrying container may further have a filling opening and a cover, wherein the iron granules and the suspended liquid are loaded into the carrying container via the filling opening, and the cover seals the filling opening.

The invention may further comprise a light source and or a light guide plate, wherein the light source is disposed inside or outside the carrying container, and generates light to illuminate the iron particle body to provide an illumination function, so that when the ambient light is weak, the light source can still be clearly seen The iron particle body in the container is carried, and the light guide plate is disposed on the side of the carrier container and close to the light source, and can be used to guide the light generated by the light source to illuminate the iron particle body.

Since the iron granules and the suspension liquid are sealed in the carrying container, there is no problem of leakage or splashing, and the iron granules are immersed in the suspended liquid, and the suspended liquid can be reduced. Part of the gravity of the light iron granules allows the iron granules to move more freely, speeding up the arrangement, and instantly providing the display function of the magnetic lines in the space and the three-dimensional shape.
