all i can find on the internet are the attractive and repulsive forces between 2 magnets... where can i find the relationship between distance and attractive force , between a magnet and i.e. a piece of iron?
The attraction between magnets and ferromagnetic materials is due to the alignment of magnetic domains within the material. These magnetic domains are microscopic regions where the atoms are aligned in the same direction, creating a net magnetic field. When a magnet is brought close to a ferromagnetic material, the magnetic fields of the two objects interact, causing the magnetic domains in the material to align with the magnetic field of the magnet. This alignment creates a strong attractive force between the two objects.
The strength of the attraction between a magnet and a ferromagnetic material is inversely proportional to the square of the distance between them. This means that as the distance increases, the strength of the attraction decreases at a rapid rate. For example, if the distance between a magnet and a ferromagnetic material is doubled, the strength of the attraction decreases by a factor of four.
Yes, the attraction between a magnet and a ferromagnetic material can be blocked by other materials that are not ferromagnetic. These materials, such as wood or plastic, do not have aligned magnetic domains and therefore do not interact with the magnetic field of the magnet. This means that the attraction between the magnet and the ferromagnetic material will not be able to pass through these non-magnetic materials.
The ability of a material to be attracted to a magnet depends on its composition and structure. Ferromagnetic materials, such as iron, nickel, and cobalt, have a specific arrangement of their atoms that allows them to have strong magnetic properties. Other materials, such as copper or aluminum, have a different atomic structure and therefore do not have strong magnetic properties.
Yes, the attraction between a magnet and a ferromagnetic material can be affected by temperature. As the temperature of the material increases, the motion of the atoms within the material also increases. This can cause the alignment of the magnetic domains to become disrupted, reducing the strength of the attraction between the magnet and the material. At very high temperatures, the material may lose its magnetic properties altogether.
