Exposure to strong magnets, or magnetic interference can sometimes cause the magnetic poles of the compass needle to differ or even reverse.
13.
Electrical or magnetic interference inside a computer system can cause a single bit of DRAM to spontaneously flip to the opposite state.
14.
If you are using speakers designed for audio components, not speakers marketed for use with a computer, the problem may be magnetic interference.
15.
Here's the catch-- based on painful experience : Unless you find the cause of the magnetic interference, degaussing a screen is just a temporary solution.
16.
Noticing that buildings'magnetic distortions were leading machines astray, they eventually turned the problem around and focused attention on the magnetic interferences caused by steel structures.
17.
The framework below the airport still causes magnetic interference on the compasses of outgoing aircraft : signs on the airfield warn pilots about the problem.
18.
When used for a single, balanced line, magnetic interference picked up by the cable arrives as a virtually perfect common mode signal, which is easily removed by coupling transformers.
19.
But the company's device can be used more easily in hospitals and medical offices because it does not require expensive and cumbersome shielded rooms to block out electronic and magnetic interference.
