... pole. By convention, we say that the magnetic field lines leave the North end of a magnet and enter the South end of a magnet. If you take a bar magnet and break it into two pieces, each piece will again have a North pole and a South pole. If you take one of those pieces and break it into two, each ...

... We have presented and discussed and experimental investigation on the effects of dc and ac magnetic fields on bacterium S. aureus. It was found that as prepared, the growth dynamics is governed by an asynchronous mechanism, quantitatively unaffected by a weak dc or low-frequency magnetic field. Howe ...

The difference between compasses designed to work in the northern and southern hemispheres is simply the location of the “balance”, a weight placed on the needle to ensure it remains in a horizontal plane and hence free to rotate. In the nort ...

... Iron, cobalt, nickel, and rare earth alloys exhibit ferromagnetism. The so called exchange coupling causes electron magnetic moments of one atom to align with electrons of other atoms. This alignment produces magnetism. Whole groups of atoms align and form domains. (See Figure 32-12 on page 756) A m ...
