Diamagnetic substance are characterised by
a)low,negative magnetic susceptibility
b)low,positive magnetic susceptibility
c)high,negative magnetic susceptibility
d)high,positive magnetic susceptibility
Answers
option b
..................
Answer :- low,positive magnetic susceptibility
Explanation: According to their magnetic properties, there are three basic kinds of substances: diamagnetic, paramagnetic and ferromagnetic. Magnetic properties depend on the structure of the electron cloud of the atom and on the structure of atoms in the substance. Paramagnetic and ferromagnetic substances consist of the same kind of atoms, but they are arranged differently.
Diamagnetic substances:- have relative permeability slightly smaller than one (that is, their susceptibility is negative), which means they slightly weaken surrounding magnetic field. If we put a magnet close to a diamagnetic substance, it will be slightly repelled. Diamagnetic substances are for example water, bismuth, graphite, copper or mercury.
