The property of paramagnetism is find in these substances whose atom have excess of electrons Spinning in the same direction . Hence atom of paramagnetic substances have a non-zero magnetic moment.
In a case such as hydrogen, where there is only one electron in the s orbital (or s state), the orbital motion's contribution to the magnetic effect is zero, and the diamagnetic moment is mainly that of the spin. In some materials, such as semiconductors and metals, free electrons also...
The orbital motion of an electron around the nucleus can be equated to a current in a loop of wire having no resistance. The magnetic moment of an electron, due to this motion, is as (4.5)μo=(area of loop)(current in emu) According to Bohr's theory (1913) of atom the electron ...
properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons. A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or ...

Consequently there are in deoxyhaemoglobin four unpaired electrons per iron atom leading to a paramagnetic moment of 5.35 Bohr magnetons per haem group. Oxyhaemoglobin on the other hand is diamagnetic. Other iron-containing haemoproteins such as ferrihaemoglobin have been shown by magnetic ...
When the internal magnetization is parallel to the applied magnetic field, no force or moment is generated (pieces A and C). However, if the internal magnetization is placed at a given angle with respect to the applied magnetic field, the magnetic pieces B and D will experience torques, but...
The magnetic moment of an electron spin is considered as one unit of magnetic moment. This is called Bohr magneton (BM) and has a value of 9.27×10−24 Am2 or JT−1. The iron atom as part of the crystal has a magnetic moment of 2.2 BM. Cobalt and nickel have magnetic moments ...
