Floating type left hand rule demonstrator

Abstract

The invention provides a floating type left hand rule demonstrator. The buoyancy is utilized, a hanging wire is omitted, and in addition, the gravity is counteracted, so the phenomenon is more obvious. In order to solve the technical problems, the floating type left hand rule demonstrator adopts the technical scheme that two floating objects are respectively arranged in two water tanks fully filled with conducting liquid. One conducting wire is lapped on the two floating objects and passes through the floating objects to be in contact with liquid in the water tanks. A magnet is placed between the two water tanks, and one conducting wire is respectively led out from each water tank and is connected with a power supply. After the power supply is conducted, the electrified conducting wire receives the translation thrust under the effect of the magnetic field.

Description

technical field [0001] The invention relates to an instrument for verifying the left-hand rule, in particular to verifying the left-hand rule by using a floating object carrying a wire on a liquid to carry out translation. Background technique [0002] The current left-hand rule demonstrator is to suspend the energized wire in the magnetic field. After the energization, the wire is not only subjected to the force in the magnetic field, but also interfered by the gravity of the earth and the tension of the hanging wire, which makes the experimental phenomenon not obvious. Contents of the invention [0003] The invention provides a floating left-hand rule demonstrator, which uses the buoyancy to omit the hanging wire, and counteracts the gravity of the earth to make the phenomenon more obvious. [0004] The technical solution adopted by the present invention to solve the technical problem is: two water tanks filled with conductive liquid each have a floating object. A wire ...
