Stronger electromagnet: More conductive wire material, More electric current through the coiled wire, Pure iron or steel, ferromagnetic core/screw, More coils of wire around the ferromagnetic core
Weaker electromagnet: Less conductive wire material, Fewer coil wire around the ferromagnetic core, Core that is coded in waterproofing enamel material, Less current through the coiled wire
How can you change the strength of of an electromagnet? There are four answers for each column.
Stronger electromagnet// Weaker electromagnet
Less conductive wire mater, copper
More conductive wire material
Core that is coded in waterproofing enamel material
Fewer coil wire around the ferromagnetic core
More electric current through the coiled wire
Pure iron or steel, ferromagnetic core/screw
Less current through the coiled wire
More coils of wire around the ferromagnetic Core
