A joint of the same thermoplastic to be welded or compatible with it, containing ferromagnetic particles, is located between the two surfaces to be welded. When passed through an induction coil, this joint melts and causes melting of the surfaces in contact. 

FIGURE 11.9 Plot of the magnetic field needed to demagnetise ferromagnetic particles (coercivity, //c) as a function of particle size. The particle becomes single domain at radius Dc. 

BITTER PATTERNS. A method for detecting domain boundaries at the surface of ferromagnetic crystals. If a drop of a colloidal suspension of ferromagnetic particles is placed on the surface of the crystals, the particles will collect along the domain boundaries where the field is strongest,... 

A ferrofluidic magnetic micropump was constmcted on a Si chip. Operation relies on the use of magnetically actuated plugs of ferroliquid (a suspension of nano-sized ferromagnetic particles), which is immiscible with the pumped fluid [301],... 

In this approximation, unlike the general case, the harmonic amplitudes are determined by a single self-similar argument Co/aig. Note also that for the suspensions of ferromagnetic particles, where the hysteretic remagnetization process is possible, Eq. (4.377) holds only if an additional condition...
