Abstract
An explicit solution of the third order differential equation of motion of an electromagnetically damped reluctance seismometer is obtained for the case of greatest interest, i.e., when the terminating resistor is adjusted to give greatest damping. This solution shows that definite inter‐relationships among the instrument constants are necessary for appreciable damping. The theoretical limitations on the maximum damping which can be obtained are discussed.Keywords
