Abstract

The invention provides a model ship driven by magnetofluid. The model ship further comprises a ship body and further comprises following devices connected with the ship body: an electric field generating device and a magnetic field generating device, wherein the electric field generating device is used for generating an electric field below the bottom of the ship body; the direction of the electric field is vertical to the vertical direction of the ship body and is parallel to the transverse direction of the ship body; the magnetic field generating device is used for generating a magnetic filed below the bottom of the ship body; and the direction of the magnetic field is vertical to the vertical direction and the transverse direction of the ship body. According to the invention, acting force in an opposite direction can be applied to seawater in a magnetofluid pipeline by adjusting the directions of the electric field and the magnetic field below the bottom of the ship body. Accordingly, as a physics teaching tool, the model ship can be used for explaining how the ship body is driven in two driving manners of flow jetting driving and friction driving, so that students can understand the left-hand rule and the magnetofluid in a vivid manner.

Description

technical field [0001] The invention relates to teaching aids, in particular to model ship teaching aids in physics teaching, in particular to a model ship driven by magnetic fluid. Background technique [0002] Magnetic fluid, also known as magnetic liquid, ferrofluid or ferrofluid, is a new type of functional material, which has both the fluidity of liquid and the magnetism of solid magnetic materials. It is usually a stable colloidal liquid composed of magnetic solid particles with a diameter of nanometers (less than 10 nanometers), a base carrier liquid (also called a medium) and a surfactant. Sea water, for example, is a ferrofluid. The fluid has no magnetic attraction when it is static, and it shows magnetism when an external magnetic field is applied. Because of this, it has a wide range of applications in practice and has high academic value in theory. [0003] Magnetic fluid drive means that a magnetic field is built in the area that penetrates the seawater. This ...
