visitors this year: 39 Magnetic fields The magnetic field sensor responds to a magnetic field. In this experiment the sensor is moved through Helmholtz coils and the variation in field is measured. Apparatus Clamp...
visitors this year: 96 You can ‘see’ magnetic fields using iron filings. You can measure the strength of magnetic fields using a magnetic field sensor connected to a computer. How, for example, does that...

rogerfrost.com is a compendium of ideas for using technology with sciencey questions in mind. Started in 1995 to offer ideas to school science teachers, Roger Frost expanded the coverage to home automation, gadgets and sensors to measure, or understand, what’s going on around him.
To find things the search box, the menu and the keywords work perfectly (and we’re totally free as in advert free).
Roger Frost has been writing about technology since 1988 and this web includes articles; radio interviews with scientists and tutorials to use technology at home and the classroom.
