1V DC Interchangeable Dial for Demonstration Meter Waves & Oscillation_Sound & Resonance regenerative braking with motor-generator #2

regenerative braking with motor-generator #2

sized for short-pitch breadboard wiring where stackable plugs let multiple leads share a single terminal

Demonstrates how current through a coil produces a controllable magnetic field

Range 10Hz to 300Hz/sec

and a reinforced rim to protect against accidental impacts

1V DC Interchangeable Dial for Demonstration Meter Waves & Oscillation_Sound & Resonance regenerative braking with motor-generator #2One volt DC scale on a 315x115mm laminated panel with sealed multiplier, reconfiguring the demonstration meter as a low voltage voltmeter for single cell and battery pack readings.
