Variable Electromagnet Subcategory_Pitchers suited to fieldwork in geography

suited to fieldwork in geography units and orientation activities outside the classroom

Virtually unbreakable ABS-plastic dynamics cart pair with two-level spring punches

An 18mm pole gap on this 37 x 13 x 10mm Alnico U-shape concentrates field strongly enough to bend filings into clear field lines

configured to demonstrate Faraday's law and the principle behind transformer action

Designed for science experiments but can also be used in heaters and electrical appliances

Variable Electromagnet Subcategory_Pitchers suited to fieldwork in geographySix tappable coil counts (100, 200, 300, 400, 500, 600 turns) and a load hook beneath the core let students isolate the effect of turns from current on electromagnet pull force.
