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.

Coughing and wrapped up warm and tightly as he still has the flu, Lee pads into class and sits in the back so as not to infect anyone. He takes terrible notes and worries about infecting his partner.

Really.

Draco moves over to sit next to Rory. He smiles at her.

"Well, this doesn't look too hard." he says.

Rose signs in and sits down by Bridge, offering to be his partner.

"Hey! Fellow mischief-hunter!" Bridge grins at Rose. "So, shall we get building?"

[aroseintime.livejournal.com]

Rose gives him a smile and says, "Alright then. Hope you know what you're doin'. Don't have a much of a clue, myself."

"No problem, dude. Building things is what I do best!"

Thomasina signs her name to the class roster and takes her seat at the lab table she habitually shares with Rose. She looks over the material associated with the experiment whilst she awaits her laboratory partner's arrival.
