Why Do Magnets Stick To Granite

Oxides of iron and titanium are responsible for this.

Why do magnets stick to granite.

Well what do you know it appears that granite is magnetic something i hadn t realised until now. Some materials such as lodestones create a persistent magnetic field. Even if the surface was roughened before attempting to stick the granite the granite itself is extremely solid making it problematic to stick. Especially if it is mined from india.

Magnets are surrounded by a magnetic fi eld. This process is very weak on granite and even the bond is doomed to fail as it cures extremely hard with no flexibility. We have some useless fridge magnets shaped like giant clothespegs to clip notes reminders shopping lists to useless since they get knocked off the fridge fall to the floor and the magnet pops out of the casing. If all of the unpaired electrons spin in random directions the object s magnetic field is either very weak or missing.

If you bring rare earth magnet towards it the magnet attracts. While i was getting some neodymium magnets ready to use i put them down on my granite surface.

Others with unpaired electrons such as iron can become magnetized when they re placed within a magnetic field and their atoms rotate and align. If you have a granite that appears tobe magnetic have it checked for magnetite or other magnetic minerals. Granite is intrusive which means that the magma was trapped deep in the crust and probably took a very long time to cool down enough to crystallize into solid rock. This is the area around the magnet where the force of the magnet acts.
