Flexible Electrical Wire Graduations_Ungraduated sized to keep electromagnetism demonstrations

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

and upper airway structures in a single anatomical plane

Center-zero galvanometer reading 1-0-1mA at plus-or-minus 2

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

this premium calorimeter delivers accurate specific-heat and heat-of-reaction measurements

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.
