... Summary: A considerable amount of empirical information about magnetism was discovered using permanent magnets. This allowed for the construction of some useful devices using permanent magnets long before any theory of magnetism existed. However, the connection between the phenomena of electricity ( ...

This problem provides an illustration of what can be meant by the statement that “magnetic forces do no work,” as discussed in sec. 5.1.2 of [1].2 We show this statement holds only if “magnetic forces” means the effect of both magnetic Lorentz forces and torques on electric charges (and not on their ...

Magnetotactic bacteria

Magnetotactic bacteria (or MTB) are a polyphyletic group of bacteria discovered by Richard P. Blakemore in 1975, that orient along the magnetic field lines of Earth's magnetic field. To perform this task, these bacteria have organelles called magnetosomes that contain magnetic crystals. The biological phenomenon of microorganisms tending to move in response to the environment's magnetic characteristics is known as magnetotaxis (although this term is misleading in that every other application of the term taxis involves a stimulus-response mechanism). In contrast to the magnetoception of animals, the bacteria contain fixed magnets that force the bacteria into alignment — even dead cells align, just like a compass needle. The alignment is believed to aid these organisms in reaching regions of optimal oxygen concentration.
