Permanent electric dipole moments (EDMs) of fundamental particles provide powerful probes for physics beyond the Standard Model. We propose to search for the EDM of strange and charm baryons at LHC, extending the ongoing experimental program on the neutron, muon, atoms, molecules and light nuclei. The EDM of strange 
baryons, selected from weak decays of charm baryons produced in 
collisions at LHC, can be determined by studying the spin precession in the magnetic field of the detector tracking system. A test of 
symmetry can be performed by measuring the magnetic dipole moment of and 
baryons. For short-lived 
and 
baryons, to be produced in a fixed-target experiment using the 7 
LHC beam and channeled in a bent crystal, the spin precession is induced by the intense electromagnetic field between crystal atomic planes. The experimental layout based on the LHCb detector and the expected sensitivities in the coming years are discussed.
