This is a good question and a bit tricky to answer but i ll try my best.

Why does a magnet stick to granite.

Power grab n bond is a phenomenon in structured adhesives. Dean age 7 vermont sth. Well what do you know it appears that granite is magnetic something i hadn t realised until now. Probably magnetite an fe containing mineral.

Well there goes that theory. 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. Especially if it is mined fromindia. Oxides of iron and titanium are responsible for this.

Granite is mainly quartz feldspar and mica which are non magnetic and hornblende which varies a lot in composition but which usually includes some fe though not enough to excite a fridge magnet you wouldn t think. It increased most quickly during the earliest days of each step. Any jam or marmalade on the granite.

If you bring rare earth magnettowards it the magnet attracts.

It will stick granite immediately and create a formidable bond. While i was getting some neodymium magnets ready to use i. The growing magnetism of the samples suggests that the heat triggered reactions that caused some of the pyrite to chemically transform into magnetic minerals. Iron oxide is a fair permanent magnet ferrite magnets so if there is iron oxide in the granite it will be weakly magnetic unless.
