The invention relates to the technical field of science popularization education, in particular to an ampere force demonstration interactive device applicable to places for popularizing science. The ampere force demonstration interactive device comprises a box and a fixing frame arranged on the box, a first permanent magnet and a second permanent magnet are mounted on the fixing frame in a vertically overlapped state, an N pole of the first permanent magnet is opposite to an S pole of the second permanent magnet, a gap is reserved between the N pole of the first permanent magnet and the S pole of the second permanent magnet, a bearing is arranged at the center of the box, a copper disk penetrates the gap between the N pole of the first permanent magnet and the S pole of the second permanent magnet and is mounted on the bearing in a movably rotating state, one end of a driving lever is arranged outside a protective cover and connected with a first lead, the other end of the driving lever is arranged on the fixing frame and provided with a contact, the center of the copper disk is connected with a power supply through a second lead, and an ampere meter is connected with the first lead and the second lead to form a loop. The device is simple to operate, easy to maintain and suitable for conveniently popularizing ampere force knowledge in the places for popularizing science.
Description
technical field [0001] The invention relates to the technical field of popular science education, in particular to an Amperex demonstration interactive device suitable for popular science venues. Background technique [0002] The force experienced by a current-carrying wire in a magnetic field is called the Ampere's force. It is an important knowledge in electromagnetism in high school. In order for students to understand the Ampere force intuitively, many kinds of Ampere force demonstration devices have appeared. For example, patent publication numbers CN 102298867 A, CN101520957 A, CN102376186 A, CN 204155523 U, CN 101221707 A and other patents have all done research on different demonstration methods of Amperex, but what they have in common is education suitable for school teaching Category; combined with the current situation of domestic science and technology venues, due to the unsystematic structure of the device and the difficulty of maintenance, the content involved...
