To investigate, describe and recall how the strength of the magnetic field ... turns in the coil and the material used as the core of the coil. The main variables in a science experiment are ...

In this facility a conductive sample is placed in a coil and processed containerless ... scientists to process the sample without contact to a crucible and with low magnetic field strengths compared ...

A second experiment can be carried out to investigate how the strength of the electromagnet depends on the number of turns in the coil. As the number of turns increases the number of paper clips ...
