Using Li?ard's generalization of Larmor's formula shows that it is sharply peaked in the forward direction.  
The quenching of its low-frequency component in plasmas due to the disappearance of the beaming effect is known as the Razin effect.  Using Li?ard's generalization of Larmor's formula shows that it is sharply peaked in the forward direction.  It is the mechanism of emission in the lobes of radio galaxies and in the diffuse part of the Crab Nebula.  It is generated by relativistic electrons; as the electrons radiate, their radii of gyration steadily decrease.  FTP, name this type of radiation produced by relativistic electrons spiraling around magnetic field lines.
