Subject: Magnets and Sea Urchins
One of my into E&M students bowwored a Pasco Hemholtz coil and Power
supply for her
biology project. She put sea urchins in a magnetic filed for their first
two weeks of growth.
They developed fine, but almost twice as fast as normal.
At the maximum continous current I measured a field of 30 gauss.
