Portable Digital Ammeter, 0-10A Biology_Entomology & Zoology Used to measure induced EMF

Used to measure induced EMF as a magnet falls through a 100-turn coil on a 15mm acrylic tube

Electromagnet-driven at approximately 80Hz with a captive thumbscrew on one prong for Melde's experiment

Insulated 2mm-plug lead in the small-scale lead family

Sectional 3D plant cell model exposes cell wall

Hand-driven Newton's color disc that spins seven painted segments fast enough to merge into apparent white through persistence-of-vision and additive color mixing

Portable Digital Ammeter, 0-10A Biology_Entomology & Zoology Used to measure induced EMFLarge LCD portable digital ammeter measuring 0 10A, providing a direct numeric current reading for student circuits where analog needle deflection would be too coarse to resolve cleanly.
