Classroom Wave Form Helix Spring Subcategory_Bases and Rods this polypropylene graduated cylinder set

this polypropylene graduated cylinder set is Class B-tolerant

sized for low-current circuit work below the 1A range where finer resolution matters more than full-scale capacity

varying length isolating density as the single variable across materials

sized for a complete length-versus-strength comparison study using one consistent material

this 6-inch Alnico bar pair extends field lines visibly along the magnet body for full-class iron-filing demonstrations

Classroom Wave Form Helix Spring Subcategory_Bases and Rods this polypropylene graduated cylinder setWide 7. 5cm coil diameter on a 5cm closed length helix, producing slow, large amplitude waves that students can resolve when oscillating the spring by hand for transverse wave studies.
