If plants generate magnetic fields, they're not sayin'

If plants generate magnetic fields, they're not sayin': They established, however, that the plant generated no magnetic field greater than a millionth the strength of the magnetic field surrounding us here on Earth...
"There is a lot of activity now by scientists studying biomagnetism in animals, but not in plants," said Dmitry Budker, UC Berkeley professor of physics. "It is an obvious gap in science right now..."
Because magnetic fields are created by moving electrical charges, such as a current of electrons, the researchers thought that rapid processes in the plant during the rapid heating might involve flowing ions that would create a magnetic field.
