Notice anything interesting?

While I’m quite tired, I took a couple of interesting pictures whilst on campus today. These particular pictures were taken on my way to work of the back of the Brain Imaging Center. I passed by this place everyday for three years, without ever noticing what my friend pointed out to me a few weeks ago.

How about now?

How about now?

Those poles were not designed to contour with the design on the back of the MRI center, I assure you. That would be the effect of stray magnetic field from a 4 Tesla magnet. While it’s not immediately dangerous, I wouldn’t recommend prolonged exposure.  I particularly like the cautionary sign advising of the high magnetic field, conveniently placed in a central location.
