MOSEM Project

Teaching Minds-On Experiments on Electromagnetism in Secondary Schools

Scientific coordinator: Nicolaus Copernicus University in Toruń

Coordinator: Prof. Grzegorz Karwasz; Low-tech Kit: Dr Andrzej Karbowski

List of experiments:

Permanent magnets

• Chaotic magnetic pendulum
• Magnetic construction sticks and balls
• Set of toy magnets (illustrating multipoles) + fluxdetector
• Atomic force microscope model
• Tile of 5 magnetic rings around a stick
• Magnets floating on water
• Attracting force: measurement with springs
• Repelling force: measurement based on gravity
• Measurement of component of magnetic field
• Study of magnetic field with filings
• "Ski jumping” in a magnetic field

Electromagnetism
