The e.m.f. induced in a seismometer coil is proportional to:

  1. the temperature of the rock
  2. the size of the case
  3. the mass of the Earth
  4. the rate of relative motion (velocity) between the magnet and the coil
Answer

D) the rate of relative motion (velocity) between the magnet and the coil

Faster motion, larger e.m.f. SLO P-09-E-43 · Application
