Magnetism
Hey, after all, this IS the Physics Forums!
This week, the main subject of your photo must show something that has a magnetic field, or with the designed purpose of producing a magnetic field. So a permanent magnet or a solenoid will qualify. A clear depiction of a MRI facility also qualifies. A power generating turbine? Why not? A dynamo? Even better!
Please make sure that the subject can easily be recognized as having a magnetic field or is designed to produce a magnetic field.
Contest Rules:
1. Any digital photo or digitally-scanned photo relevant to the theme will be accepted within the contest period. In case there's a gray area, or you're not sure if the picture is suitable, check with me first.
2. Please resize your digital photo to no more than 800 x 600 or 600 x 800 pixels. You may also crop your picture if you wish. You are also allowed to adjust the brightness and contrast of your picture but these should not dramatically alter the look of the picture. But other than those, any form of picture editing or modification is not allowed. This is a photo contest, not a picture editing/special effect contest. You may add a watermark or your name/nickname to the photo for identification purposes.
3. Upload your photos to any of the photo servers such as imageshack or photobucket. Then post it the relevant contest thread and link your picture using the img command. PM me if you do not know how. Alternatively, you may simply upload your image file to PF, and then have the full image displayed in your post.
4. Only ONE picture per member per contest. Once a picture is posted, it cannot be changed other than a total withdrawl by that member from that week's photo contest. Exceptions will be made for modification to comply with the rules, such as resizing.
5. At the end of the contest period, I will open a poll and every PF member can vote for the picture they like best.
6. Note that in case we have a large number of entries, I will do the polling in more than one thread. If that's the case, you can vote in each of the polling threads. The photos will be assigned in the polling threads in the order they were submitted.
7. The photo of the subject must be something that you took directly, not via in intermediary medium, and not taken by someone else. Unless otherwise noted, a photo of another photo, painting, print, etc. does not qualify.
8. You can use a picture only once. Once it is used in a contest, it cannot be reused in another contest.
9. Please post only pictures meant for submission in this thread. Photos not meant for submission must not be posted in the contest thread. Posting of more than one photos by a member may result in an automatic disqualification from the week's contest.

Sorry, it looked just like the others on my screen but now I am seeing when I click on it it enlarges and the others don't. I will have to return to the external hosting system since the seemingly convenient PF upload does this. (Unless there is some trick I am missing.)
... somehow or other I got the image into Preview tools I think somehow. Don't think I could control the size of the picture but I could give the number of pixels, the required 800X600. However I have no way of checking this has worked, Info on the picture does not tell me Pixels.
