Group 4 project on physics help?

Recommended Posts

So, just a quick question. Our theme, for the Project 4 is : IRON. We need to come up with some exercises with iron and everything I could come up with is spectrophotometry (which isn't even connected to physics in general - mostly chem...). Any help, please? :)

For a physics project, you could carry out an experimental investigation of some of the magnetic properties of iron. For example, you could plot the hysteresis loops for soft and hard iron rods on which you have wound a coil to provide the magnetizing field. Rather than use a commercial instrument to measure the flux density, you could make your own simple deflection magnetometer with a compass needle.

Wooow, thanks! But I'm new in this field, we haven't done much about that. Is there any article or anything on the web right now that I might find useful? About the method you are suggesting? :)

Yes, you should find plenty of information in school physics books or on the web by searching for terms like "magnetic hysteresis" or "B-H loop". With this project it should be easy to adjust the depth of your study to suit your experience, the time available, and your school lab facilities.
