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 ...

University of North Carolina Chapel Hill researchers have found that captive loggerheads could be conditioned to “dance” by associating certain magnetic fields with being fed food.

Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to ...

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 ...
