Is Inverse-Square Law responsible?
With respect to the thesis that it is impossible to create a local region of higher magnetic intensity in free space using magnetic dipoles, is this not due to the inverse-square law?
For example, cancer tumors are treated using the principle of...
I have been asked to prove or disprove the following problem:
Is it possible to arrange an array of magnetic dipoles (little magnets) in free space such that the magnetic field at the centroid of the space is higher than the field strength immediately surrounding the centroid? The field...
I just reread your post and I think we are trying to do the same thing. See my post, "Are magnetic bubbles possible?".
If a magnetic field can be collimated and sent like a beam of light, then a magnetic bubble can also be created.
If it is impossible to collimate a magnetic...
mu-metal is used as a shield against weak magnetic fields, such as the Earth's field, in scientific instruments where a weak field is a problem. mu-metal is used in oscilloscopes using cathode-ray tubes.
If the mu-metal is arranged as an enclosure, then incident magnetic lines will follow...
