Geology

Good morning. Feel free to help yourselves to the doughnuts. No coffee--I need to get a new machine. And please remember that our cumulative final will be next Monday.

Today, we will be doing an experiment in magnetic relaxation.

A magnetic compass is a device that tells us what direction is North. It does this by aligning a small magnet, the compass needle, with the magnetic field of the earth. The compass can be used to detect more than just the magnetic field of the Earth. In fact, it points in the direction of the strongest magnetic field in the area. If you bring a permanent magnet near a compass and move it around, the compass will react. In this experiment, we will use a compass to study the rate at which a temporary magnet relaxes.

You and your partner(s) will build an electromagnet and then do the experiment I am passing around now.
