Impedance at different frequency...... impedance decreases with increasing frequency, any one has work with fibers and metal particles ...?
What factors that can increase or decrease the coercivity? For example, particle size affects the coercivity; if we use long nickel fibers than in this case what factors influence the coercivity....
