... A house has a floor area of 112 m² and an outside wall that has an area of 28 m². the earth’s magnetic field at that location has a horizontal component of 2.6 x 10-5 T, north, and a vertical component of 4.2 x 10-5 T, down. Determine the magnetic flux through the wall if the wall faces (a) north, a ...

... The physical picture: • Put some salt into the water (either NaCl or CuSO4), about 5-10%. Therefore we have the electrolyte: H2O + NaCl=>Na+ + ClThe positive and negative ions begin to move in the radial direction but the magnetic force acts perpendicular to the ion’s trajectory. Hence the water st ...

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.
