That proved to be a sensitive detector of magnetic fields, like those used to store information on hard disks, and in 1997, I.B.M. introduced the first hard disk that took advantage of giant magnetoresistance.
It can't move easily through the crystal, but it can align with magnetic fields like a compass needle that is, it is in a magnetic state.
In this pressure region, breakdown voltages for most gases have minimum values without the help of magnetic fields like a magnetron.
This first magnetic map of another star, to be published in next month's issue of Astrophysical Journal Letters, suggests that at least some stars have magnetic fields like those of Earth and the sun.
After the cell growth, 25 mL of Paenibacillus sp. cell suspension was taken in a test tube and treated it with different magnetic fields like 100, 300 and 500 mT with different time period such as 0, 5, 10, 20 and 30 min.
Finally, the fragment might have caused potentially serious problems in instances such as the placement of a new epidural catheter, or the excessive heating that might result from exposure to strong magnetic fields like those of magnetic resonance imaging [ 19].
