Question

All final numerical answers must have the correct units, correct number of significant figures, and correct vector notation (where appropriate). It has been asserted that a permanent magnet is really just made up of an insulator with fixed positive electrical charges permanently embedded in the north pole of the magnet and fixed negative electrical charges permanently embedded in the south pole of the magnet. Do you believe this assertion? Name three observations you made in Unit 26 that would provide support for or evidence against this assertion. Cite Activity numbers and explain how each observation support your conclusion.

Explanation / Answer

Reason for this assertion :

Magnets posses mechanically and chemically fixed electron biases. That is, electrons would appear to be trapped toward one side of the atoms and molecules that make up fixed magnets.

This fixing means that one end of the magnet has a relative surplus of negatively charged electrons. The converse holds true, where positively charged atomic nuclei are relatively bare. As this is at the molecular level, one can split a fixed magnet and the polarization remains for both fractions of the original magnet.
