5 Facts On Is Graphene & Graphene Oxide Magnetic?

Graphene is an allotrope of graphite that is made up of carbon. In this article, we shall talk about the magnetic behavior of graphene and its oxide.

Graphene is purely made up of carbon and hence is nonmagnetic because carbon is diamagnetic, having all electrons paired even in the valence orbital 2p, forming the C-C metallic bonds. Graphene oxides are magnetic because they are nanoparticles and become magnetic inside the body.

Graphene is a good conductor of heat and electricity and thus finds its use in electronics, batteries, sensors, transistors, etc. We shall further discuss the magnetic properties of graphene, graphene oxide, and also graphene hydroxide in detail, and the fact behind the rigidity of graphene.

Why is graphene not magnetic?

The magnetic property of any substance depends upon its chemical structure and bonding. Let us talk about the magnetic behavior of graphene.

Graphene is not magnetic because it is wholly composed of carbon atoms bonded in a hexagonal patterned structure and is diamagnetic. The diamagnetic behavior of graphene is due to the presence of carbon atoms whose unpaired electrons in the 2p orbital pair up during the metallic bond formation.

Is graphene oxide magnetic?

Graphene oxide is an oxidized form of graphene which is dispersible in different solvents. Let us discuss whether graphene oxide is magnetic or not.

Graphene oxide is magnetic and shows variant magnetic behavior. The graphene oxide gets attracted towards the magnet forming the spin-like structure across the area of the magnet. Due to its magnetic property, it is used for the adsorption of metals and radionuclides. It is nonconductive oxide metal.

a. How is graphene oxide magnetic?

Graphene oxide is magnetic due to the dispersion of π -electrons and sp3 hybridized carbon molecules. These π-electrons are free to move and align in the direction of the magnetic field, increasing the graphene oxide’s magnetic moment, and giving it ferromagnetic characteristics.

Graphene oxide magnetic properties

Graphene oxide (GO) shows profound magnetic characteristics, and its behavior varies under different conditions. Let us list some of the graphene oxide magnetic properties.

  • GO has a negative curie temperature.
  • The magnetization of GO is between 0.38-0.42 emu/g.
  • GO align the π-electrons in the direction of the magnetic field.
  • The magnetic dipoles of GO align in the direction of the external magnetic field.
  • GO shows paramagnetic behavior at high temperatures.

Is graphene hydroxide magnetic?

A graphene hydroxide is a single-layered activated carbon that is 0.1 nm thick and 50 nm long. Let us illuminate the fact of whether graphene hydroxide is magnetic or not.

Graphine hydroxide is nonmagnetic because it is diamagnetic due to the presence of activated carbon. The hydroxide bonds are the strongest, and there are no free electrons to boost the magnetization of graphene hydroxide.

How is graphene the strongest material?

Graphene comprises a single-layered honeycomb pattern formed by carbon bonds and is stronger than steel. Let us discuss what makes graphene the strongest material.

Graphene is the strongest material due to its flat planar structure that makes it easy to bend, is the most flexible, and does not break apart. The charges generate a strong electrostatic force of attraction that holds graphene together. The carbon bonds are very strong, and these bonds do not overlap.


We can conclude from this article that graphene is not magnetic and holds diamagnetic characteristics. The graphene oxide is magnetic and shows ferromagnetic behavior due to its sp3 hybridization and π-electron availability. Its hydroxide does not yield magnetic behavior.
