Description

Set for studying the magnetic field}

The present invention relates to a magnetic field learning set, and more specifically, by using one learning set, the magnetic field line experiment, the compass experiment, the magnetic levitation experiment, the magnetic levitation train operation, and the play experience using the magnetic ornaments can be performed simultaneously. The present invention relates to a magnetic field learning set, which has a very high learning effect, easy to handle a learning set, and can reduce equipment purchase cost.

In physics practice, the magnetic field exerts various physical phenomena as the magnetic field lines change. In the way that primary and secondary students experience these physical phenomena, the very simple theory recognizes that the same poles are repulsive and the other poles are attracted to each other. I am experiencing the simple theory of pushing against.

However, since such a simple experience makes it more difficult to understand the magnetic field, various auxiliary experimental tools and teaching aids have been proposed to assist in understanding the magnetic field.

An example of such a teaching aid may be a levitation rod made using the principle that the other poles repulse each other.

Such teaching aid has magnets having a single polarity inside the rod body, and further magnets having the same polarity as the embedded magnets are embedded in the bottom of the body, thereby repulsing between the magnet at the bottom of the body and the magnet inside the body. By acting, the rod is suspended in the air, and in this state, the rod is rotated to observe and learn the phenomenon.

Since there is little friction between the rod and the body that is held in the air by the magnetic repulsion, the rod can be rotated with a small force, and the rotational force acts permanently, and it can be directly confirmed through the test. Will be.

On the other hand, a magnetic field learning apparatus is disclosed in Korean Utility Model Registration No. 20-0438962 so that the tester can change the strength and direction of the magnetic lines of force and observe the change.

The prior art is a magnet learning device for placing a magnet on the bottom and connecting the magnet and the magnet different from the pole by a connecting rod to enable levitation by magnetic force, the magnet is arranged perpendicular to the bottom (10). After installing the horizontal adjustment plate (11) (11a) to face each other, the above. After forming the distance adjusting portion 15 in the center portion of the horizontal control plate in the horizontal direction so that the central axis 21 of the magnet 20 is covered with this distance adjusting portion, the former. Then, the stabilizer plate 30 is installed vertically to one side of the bottom surface on which the horizontal control plate is disposed, and the sharp portion 41 of the levitation magnet sphere 40 is partially pressed onto the stabilizer plate 30.
