A making method for self-made small magnetic needle

Abstract

The invention discloses a production method for a small home-made magnetic needle, which comprises a magnetic needle and a magnetic needle pedestal. Wherein, the magnetic needle is formed by cutting an audiotape into a rectangle shape, sticking it on the surface of a double-sided adhesive and bending it into a ''V'' shape. The magnetic needle pedestal is formed by passing a pin through a round cardboard. The invention has the advantages of easy-to-get materials, simple technology, and obvious effect, thus is suitable for small production for pupils.

Description

Technical field: [0001] The invention relates to an experimental equipment, in particular to a small magnetic needle used for physics teaching in high school and junior high school. Background technique: [0002] In high school and junior high school physics teaching, magnetic field knowledge is not only the teaching focus, but also the difficulty of teaching. It is very necessary for each student to make a small magnetic needle to test the existence of the magnetic field and explore the nature of the magnetic field, especially to enrich students' knowledge. The content of extracurricular experiments is very meaningful. However, the manufacturing technology of the small magnetic needles bought in the market is complicated, and the materials are not easy to obtain, so they are not suitable for students to make by themselves. Invention content: [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a self-made small magnetic...
