How can a magnet attract iron??

Dear Student
Materials have the property of conduction because of the mobile electrons in them.The electronic configuration of a particular element is responsible for the magnetic properties of the electron.The credit goes to magnetic moment of the electrons.The unpaired electrons present in elements like iron , cobalt and nickle , impart the atom its magnetic field.
This is the reason why certain material are better attracted towards magnet.The more the number of unpaired electrons , better is the magnetic field. The magnetic field of the unpaired electrons isn't cancelled out by other electrons.

Magnet Can attract those materials which are magnetic material and iron is one of the magnetic material.

The things that we called magnetic material contains mixture of iron, Nickel and Cobalt.

Most of the things are made of iron Nickel and Cobalt only which get attracted by a magnet.

There are many magnetic materials that get attracted towards magnet but iron ,Nickel and Cobalt are the main material and every object that gets attracted towards the magnet that we called a magnetic material contains one of these particles.
