Flexible Electrical Wire Graduations_Ungraduated sized to keep electromagnetism demonstrations

sized to keep electromagnetism demonstrations running when the original coils wear out

this bare Eureka constantan wire takes advantage of the alloy's low temperature coefficient

providing dense uniform spheres for ramp-and-collision experiments where a heavier projectile is needed than the plastic marbles can provide

and upper airway structures in a single anatomical plane

Flexible Electrical Wire Graduations_Ungraduated sized to keep electromagnetism demonstrationsMultistrand PVC insulated copper wire rated to 5 amps, sized for routing around components and through apparatus where solid core wire would be too stiff to follow the bend.
