Abstract
The utility model relates to a terrestrial globe, especially a terrestrial globe which can indicate the earth magnetic field, comprising a terrestrial globe and a bar magnet disposed between the south and the north poles of the terrestrial globe. The S pole and the N pole of the bar magnet are respectively corresponded to the two poles of the terrestrial globe and are best corresponded to the positions of the two magnet poles on the terrestrial globe. The position of an earth axis of the terrestrial globe is provided with a slide track of which the surface radian is equal to the surface radian of the terrestrial globe and the slide track can rotate along the earth axis as the circle center, a compass composed of small magnet needles is disposed on the slide track and the compass can slide on the slide track. The utility model can directly and clearly reflect the knowledge of earth magnetic field and the like for people to study and learn, and is a perfect teaching tool.
Description
Technical field:
The utility model relates to a kind of terrestrial globe, especially a kind of terrestrial globe of indicating the terrestrial magnetic field.
Background technology:
Present terrestrial globe is merely able to reflect the geographical situation of earth surface, and is not easy to reflect and supply people to understand from terrestrial globe for knowledge such as magnetic fields of the earth.
Technology contents:
The purpose of this utility model provides a kind of knowledge such as magnetic field of the earth can being reflected and the terrestrial globe of the indicated terrestrial magnetic field that the confession people understand from terrestrial globe.
The utility model comprises terrestrial globe, it is characterized in that being provided with between the described terrestrial globe south poles bar magnet, the S utmost point of this bar magnet and N utmost point difference be the two poles of the earth of globe accordingly, best magnetic pole position corresponding to the two poles of the earth on the terrestrial globe, be provided with one consistently with the globe surface radian and can be the slideway that rotate in the center of circle along the earth's axis on the ground of terrestrial globe shaft position, slideway be provided with the box compass that is made of small magnetic needle that can slide on slideway.
The utility model can directly clearly reflect knowledge such as magnetic fields of the earth for people from the terrestrial globe and learn to understand, and is a kind of good teaching aid.
