... along the line joining the two poles; it is attractive between unlike poles and repulsive between like poles. Following the analogy of Coulomb's law for electric charges, we may write this proportionality in the form of an equation, but we must first define either the constant of proportionality k l ...

... restrictive and thus it is far from being optimal for a wide class of equations 1.1. If the operators 0 , 1 , and 2 on the right-hand side of 1.1 are positive then we can estimate the spectral radius of the operator A by using the well-known results due to Krasnosel’skij and we thus obtain th ...

... 12. A permanent magnet can be used to magnetise a needle or a nail by stroking it in one direction 30-40 times – a temporary magnet is created. 13. If you float the needle over a cork or polystyrene on water, the needle will point at the North pole like a compass. 14. You can also magnetise a nail b ...
