utual Inductance.—^The two coils whose mutual in-ductance, M, is to be measured, are connected up in two separatecircuits. One coil, with a battery, a key for making or breakingcontact, and a tangent galvanometer, forms a primary circuit, andthe other is connected with a ballistic galvanometer to… … -earth Fig. 325. is then t)ioken, and the throw, 6, of the ballistic galvanometer isobseived, the reading being corrected for damping if needful. If ris the total resistance of the secondary circuit (including the gal-vanometer), the quantity of the secondary current is (313) Q = MO/r; but it is…
