Vibration Generator

Vibration Generator Electromagnetic mechanical vibration — driven by signal generator input Converts electrical oscillation from a signal generator into precise mechanical vibration. A coil within a cylindrical permanent magnet field drives a threaded armature shaft — ideal for Chladni's figure experiments, resonance demonstrations, and wave mechanics investigations. Fuse-protected, thermally stable, and transport-safe with a built-in shaft lock. The Vibration Generator (SE.MS0265-01) is a precision electromagnetic transducer designed for physics demonstrations and laboratory investigations in mechanical waves and resonance. It converts an alternating electrical signal from an external signal generator into controlled mechanical oscillation, delivered through a threaded output shaft at the top of the unit. The operating principle is straightforward: the input signal is fed to a coil wound within the field of a cylindrical permanent magnet. As current alternates in the coil, the resulting electromagnetic force drives the armature — and anything attached to its threaded tip — in synchronised oscillation at the input frequency. This makes the unit highly versatile for exploring standing waves, resonance modes, and nodal patterns. Applications include: Chladni Figures Attach a metal or acrylic plate to the threaded shaft and scatter sand to reveal resonant nodal patterns at different frequencies. String Resonance Drive a tensioned string to produce standing waves and demonstrate harmonics, nodes, and antinodes. Wave Mechanics Investigate frequency, amplitude, and wavelength relationships in mechanical wave systems. Construction highlights: Coil and magnet assembly sealed against foreign particle ingress for reliable, long-term operation Specially designed coil system allows sustained operation at maximum rated input without overheating Strong base provides stable mounting during experiments; plastic enclosure is robust and lightweight Threaded armature extension accommodates a wide range of attachments and accessories Shaft locking collar prevents shaft movement during storage and transit — simply disengage before use Integrated fuse protects internal circuitry from electrical overload Pair of 4mm shielded input sockets ensures low-noise connection to signal generator output A signal generator (sold separately) is required to operate this unit. Connect the signal generator output to the 4mm sockets, disengage the shaft lock, attach your experimental object to the threaded shaft, and adjust the signal generator frequency to explore resonance phenomena.
