between salt of zinc & cobalt ,which will be affected by magnetic field.Co,Zn or none of these

Hi,

Zinc is a Diamagnetic material. Diamagnetism is the property of an object which causes it to create a magnetic field in opposition of an externally applied magnetic field, thus causing a repulsive effect. Specifically, an external magnetic field alters the orbital velocity of electrons around their nuclei, thus changing themagnetic dipole moment in the direction opposing the external field.

Cobalt is a ferromagnetic material. Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets and/or exhibit strong interactions with magnets; it is responsible for most phenomena of magnetism encountered in everyday life (for example, refrigerator magnets).
