If the object is left in one position for a long period of time it will also gain an induced magnetic field due to the effects of the earth's magnetic field. Did they make your experimental values increase or decrease. There are several sources of error in Physics Lab experiments. These include incomplete definition, environmental factors, and physical variations.

The accepted rule is that the degree of precision is ± the smallest division on the instrument, in this case one millimetre. Andrew Sproul + 14 others found this useful Edit Share to: Was this answer useful? In the absence of any local sources of ferrous material or magnetic fields a geomagnetic compass will always point to the magnetic north pole. Instruments that are not calibrated for the conditions of the experiment also cause errors.
Sources of error must be specific. "Manual error" or "human error" are not acceptable sources of error as they do not specify exactly what is causing the variations. This is not true, it is understood that experimental results are only estimates. In a scientific experiment, a source of error is something that could have caused you to obtain an incorrect result.

Automated measuring using a data-logger system can help reduce the likelihood of this error; alternatively you can take a break from measuring from time to time.Replicates and samples Because of A minimum of five sensors arranged in a pentagon are required to ensure that a voting system will always indicate a true bearing to magnetic north, although this arrangement would still
A: Quick Answer Errors in the chemistry lab can arise from human error, equipment limitations and observation errors. This figure is 2 orders of magnitude less than the typical manufacturer's stated accuracy of compass sensors and significantly less than the 10' annual change in declination.
