Magnetic moment

A

increases with increasing number of unpaired electrons

B

gives indication about the number of unpaired electrons present in the atom, molecule or ion

C

its unit is Bohr Magneton (BM). A single unpaired electron has 1.73 BM magnetic moment

D

All of the above

Text Solution

Verified by Experts

The correct Answer is:
D
The magnetic moment is determined by the number of unpaired electrons and is calculated by using the 'spin-only' formula, i.e. `mu=sqrt(n(n+2))` BM
where, n is the number of unpaired electrons and `mu` is the magnetic moment in units of Bohr Magneton (BM).
A single unpaired electron has a magnetic moment of 1.73 Bohr Magneton (BM).

The product of the length of the magnet and its pole strength is called the moment of a magnet or Magnetic moment. If 'm' is the pole strength and 2l is the length of the magnet then, the moment of the magnet or Magnetic moment is given by. M =m xx 2l . Also, Magnetic moment is a vector quantity, with its direction from south pole to north pole along its axial line. If a bar magnet of magnetic moment 80 units be cut into two halves of equal lengths the magnetic moment of each half will be
