  Magnetic susceptibility of the topological Weyl, type-II Weyl, Dirac, and
line node semimetals is theoretically investigated. Dependences of this
susceptibility on the chemical potential, temperature, direction and magnitude
of the magnetic field are found. The obtained results show that magnetic
measurements can be very useful in investigating these semimetals. As an
example, we calculate magnetic susceptibility of Cd$_3$As$_2$, Na$_3$Bi, and
Ca$_3$P$_2$.
