Will magnetic field of 12v DC micro motor mess up or destroy the memory of EEPROM chip if place it  2...3 cm away from the chip ?

Jack Christensen

Nope, the chip is silicon, non-magnetic.

I also think the eeprom will not be destroy  but not for the reason indicated: magnetism is able to change the polarization of light in a fiber optic  yet the glass is not magnetic. Magnetism is very complex.
However it may occurs interferences that affect the value of some bits and cause errors.
Only if you find any errors place a magnetic shield (soft iron) between the motor and the EEPROM

make a shield from cardboard , alu-foil and duct tape around the electronics.

That will not stop a magnetic field, so it is lucky that a magnetic field will not effect the EEPROM isn't it.
