Using an eight-terminal geometry, we have measured voltages in Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} single crystals with current injected both parallel and perpendicular to the crystallographic c axis and with magnetic fields H{le}3 kOe, {bold H}{parallel}c axis. In a range of fields and temperatures for which the conductivity is Ohmic, our results disagree with a model that assumes classical electrodynamics. We believe that interlayer vortex coupling is responsible for nonlocal conductivity in this regime. {copyright} {ital 1997} {ital The American Physical Society}
