Chapter 9 THE MAGNETIC FIELD
... flux relations show that the electrostatic field has nonzero flux for a Gaussian surface enclosing charge because charges are sources and sinks of the electric field, whereas the magnetic field has zero flux out of a Gaussian surface because there are no sources or sinks of magnetic field. The circu ...

... Challenge: Use the field meter, and make a table showing magnetic field strength (“B”, measured in “Gauss”) vs. distance from the end of the magnet. (There are no units given for position, so just use arbitrary units of “one compass away”, “two compasses away”, etc. Alternatively, you can tape a rul ...
