Is there any law similar to coulomb's law of electrostatic that shows force between magnetic poles?

More or less... Please consider that electric charges can be separated, while magnetic poles can not be separated. So, you basically always have a "magnetic dipole"; the electrical equivalent would be a positive charge, and an equivalent negative charge, separate by a small distance. The poles can't be separated; the magnets will attract each other in one orientation, and there will be repulsive forces in another orientation (i.e., if they are rotated).
The Wikipedia article - http://en.wikipedia.org/wiki/Force_between_magnets - states that "Calculating the attractive or repulsive force between two magnets is, in the general case, an extremely complex operation, as it depends on the shape, magnetization, orientation and separation of the magnets.".
However, at greater distances (compared to the size of the magnet), the force on an electric or magnetic dipole will decrease, approximately, with the CUBE of the distance.

WHY do similar sides attract on a magnet?
SIMILAR repel, opposites attract. And they are because of that because of the magnetic fields.
The gravity lock of the Moon to the Earth is similar to the action of a master key?
It's not similar to a master key..but a "magnetic compass"
What other application of magnetic fields uses properties similar to an MRI?
An XRAY.
Are magnetic forces bad for computers?
Magnetic forces are not necessarily bad for computers, as mechanical hard disks use them to store information. However, you shouldn't place any magnetic objects near them as it will ruin your data that's store on those kinds of disks.
Why magnetic field lines emerge perpendicularly from the surface of permanent magnet?
This is somewhat to similar to the ejection of electrons right perpendicular to the surface of cathode. This is due to repulsion between the like charged electrons. Same way magnetic lines of force never intersect and as they repel themselves they come out perpendicularly from the surface.
Forces that act on an object at a distance?
Some forces do not involve physical contact between the bodies on which they act. They act through the space between them. Such forces are called Non-Contact Forces or Action-at-a Distance Force. They are of three types, namely, magnetic force, electrostatic force and gravhtational force. Magnetic Force -- The forces which a magnet exerts on iron objects is called magnetic forces. Electrostatic Force -- The force which result due to the repulsion of similar charges or attraction of opposite charges is called electrostatic force. Gravitational force -- The force by which Earth pulls the objects towards its centre is called gravitational force.
How are ionic bonds like magnets?
The force of attraction in an ionic bond is electrostatic and in this unlike charges attract and like charges repel. This is similar to magnetism where opposite poles attract and like poles repel. Both electrostatic and magnetic fields obey the inverse square law.
Why are ionic bonds similar to hydrogen bonds?
Both are formed by electrostatic attraction between entities with opposite sign electric charges.
What is the mathematical form of coulombs law similar to?
newtons gravitational law is similar to that of coulomb's law...
What is the maximum magnetic variation on earth?
It will be 180 degrees in any position between the north magnetic pole and the geographical north pole and similar at the south pole
How is coulombs law similar to newtons law of gravity?
Both are 'Inverse square' forces, f=k/r2 .
What are the limitations of coulomb's law?
coulombs law is valid if the average number of solvent molecules between two interacting charges is large enough that the properties of the micro region of solvent can be expected to b similar to that of the bulk solvent.
Is Fayalite magnetic?
Yes, fayalite is magnetic, ithas a magnetic susceptibilty of approx 33 SI units, similar to prryhotite.
Is moon rock magnetic?
Moon rocks are very similar to earth rocks an they are not intrinsically magnetic.
The magnetic field of an electromagnet is similar to that of a magnet?

Is spelter magnetic?
No, spelter is not magnetic. Spelter is simply a synonym for zinc and is similar to copper or brass as well.
