Vibration Generator – Mechanical Waves & Oscillation Demonstrations

The Vibration Generator is a laboratory apparatus designed to convert an electrical signal into mechanical vibrations for physics experiments investigating oscillations, resonance and wave motion.

When connected to a suitable external signal generator, the apparatus produces controlled mechanical vibrations. The supplied spring and metal cross support practical demonstrations of vibration patterns and mechanical waves.

How It Works

An electrical signal is fed to a coil mounted within the magnetic field of a cylindrical permanent magnet. The interaction produces oscillatory motion, delivered through a shaft at the top of the apparatus. A threaded extension of the armature allows suitable demonstration accessories to be attached.

Key Features

• Electromagnetic coil and permanent magnet system for producing mechanical oscillations
• Electrical input via a pair of 4 mm shielded sockets
• Threaded mechanical output shaft for attaching suitable accessories
• Strong base and protective plastic housing
• Coil and magnet assembly protected against entry of foreign particles
• Locking arrangement to secure the shaft during storage and transport
• Electrical fuse protection
• Coil system designed for prolonged operation within its rated limits
• Supplied with a spring, metal cross and banana plug attachment

Educational Applications

• Mechanical Oscillations: Investigate periodic motion generated by an electrical driving signal.
• Wave Motion: Observe wave patterns using the supplied spring.
• Frequency and Vibration: Explore how changing the driving signal affects mechanical motion.
• Resonance: Investigate the response of a vibrating system at different driving frequencies.
• Chladni Figures: With suitable separately supplied plates and a compatible signal generator, investigate resonance and standing-wave patterns.
