| If the bit becomes too small, the magnetic energy holding the bit in place may also become so small that thermal energy can cause it to demagnetize. |
| The candidate is required to demagnetize the test specimens at the completion of the test. |
| Idle disks may start to lose data and start to demagnetize after a year or two, unless they are spun-up every 30 days. |
| The immense seismic vibrations from an impact can create temperatures high enough to melt or demagnetize some rocks in and near the crater. |
| The straightforward remedy is to adopt magnetic materials of higher coercivity, meaning they are harder both to magnetize and to demagnetize. |
| For example, once upon a time everyone knew that the tomato was deadly poison, and that one could demagnetize a permanent magnet by rubbing garlic on it. |
