Abstract: The invention relates to an electromagnetic hammer having a moving ferromagnetic mass, the hammer being of the type comprising a tube of non-magnetic material for standing on an element that is to be driven into the ground, said tube being surrounded by a peripheral coil connected to electrical power supply and slidably receiving the moving mass. According to the invention, the peripheral coil is subdivided into a plurality of independent coils, each independent coil being received in an associated casing and being wound around a cylindrical inner wall of said casing, the cylindrical inner walls of the casings being superposed to make up the tube in which the moving mass slides, each casing also taking up axial forces, and a junction box enabling the corresponding coil to be connected to associated electrical power supply cables.
