चुंबकीय क्षेत्राकडे आकर्षित होणाऱ्या  पदार्थांना ____म्हणतात. 

संकल्पना:

• Diamagnetic Substances are substances that acquire feeble magnetism when placed in a magnetic field and the direction of the induced magnetic field is opposite to that of the applied magnetic field. Examples are bismuth, copper, silver, gold, mercury etc. 
• Paramagnetic Substances are substances that acquire feeble magnetism when placed in a magnetic field and the direction of the induced magnetic field is the same as that of the applied magnetic field. Examples are aluminium, manganese, platinum etc. 
• Ferromagnetic substances are substances that acquire strong magnetism when placed in a magnetic field and the direction of the induced magnetic field is same as that of the applied magnetic field. Examples are iron, cobalt, nickel etc. 
• Ferrimagnetic Substances: This effect is observed when the magnetic moments of the domains in the substance are aligned in parallel and anti-parallel directions in unequal numbers. Ferrimagnetic substances are weakly attracted by a magnetic field as compared to ferromagnetic substances. Example: NiFe2O4, CoFe2O4, Fe3O4 (or FeO.Fe2O3), CuFe2O4 etc.

Explanation:

• Ferromagnetic metals are strongly attracted by a magnetic force.
• The common ferromagnetic metals include iron, nickel, cobalt and alloys such as steel.
• Ferromagnetic metals are commonly used to make permanent magnets.
