Abstract
The utility model belongs to the teaching appliance technical field, and especially relates to a demonstration apparatus of motion of an electrified conductor in a magnetic field. The demonstration apparatus comprises a magnet and a conductor arranged between the two poles of the magnet, floating pieces are provided at two ends of the conductor, the floating pieces are placed in a water tank filled with a conductive solution, and the water tank are connected with power supply through lead. According to the invention, the moving conductor is erected on the solution by a method, the problems of large frictional force, sparking at contact position and difficult placement for the conductor with a horizontal direction can be avoided, the motion effect is obvious, the success is easy to obtain, and the learning interest of the students can be excited.
Description
Technical field
The utility model belongs to the teaching aid technical field, relates in particular to the apparatus for demonstrating that a kind of electrical conductor moves in magnetic field.
Background technology
In middle school physical curriculum, have a lot of Physical Experiment demonstrations usually.In the effect experiment of magnetic field to electrical conductor power, because electromagnetic force is too little, friction force is relatively too big, and conductor often can not move after energising; And strike sparks and the generation oxidation easily between conductor and the track, make both contact positions become insulation, experiment is difficult for successfully; Deformation takes place in instrument base slightly in addition, and the desktop of perhaps placing instrument has injustice slightly, all can influence the direction of motion of conductor, also usually can make the failure of an experiment.
Summary of the invention
The purpose of the utility model is to solve above-described technical matters, the apparatus for demonstrating that provides a kind of electrical conductor in magnetic field, to move, and its technical scheme is following:
The apparatus for demonstrating that a kind of electrical conductor moves in magnetic field comprises magnet and the conductor that is arranged on magnet two interpolars, and the two ends of described conductor are provided with floating sheet, and said floating sheet is placed in the tank that fills conductive liquid, and described tank is connected with power supply through lead.
Optimal way is that described conductive liquid is a potassium nitrate solution.
Optimal way is that described conductor is a flake aluminum.
The apparatus for demonstrating that the electrical conductor that the utility model provides moves in magnetic field manages the conductor of motion to set up on the liquid, just can avoid that friction force is too big, contact position sparking and be difficult to make conductor to be in problems such as horizontal positioned.The two ends of conductor are inserted respectively in two tanks that conductive liquid is housed, again the two ends of power supply are received respectively on the electrode of two tanks, and conductor is in the magnetic field, energising, this moment, conductor will move.
The utility model manages the conductor of motion to set up on the liquid, has avoided that friction force is too big, contact position sparking and be difficult to make conductor to be in problems such as horizontal positioned, and movement effects is obvious, success easily, and can motivate students' interest in learning.
