Quotation

3275. Though the physical lines of force of a magnet may and must be considered as extending to infinite distance around it as long as the magnet is absolutely alone (3110.), yet they may be condensed and compressed into a very small local space, by the influence of other systems of magnetic power. This is indicated by fig. 6. I have no doubt ... [that the total power of the compressed field of two square inches is the same as the total power of the infinite field of the small magnet in free space].   Google-1   Google-2
