Abstract The total current of Ca 2+ ions through patch‐clamped cell membranes was measured while exposing clonal insulin‐producing β‐cells (RINm5F) to a combination of DC and AC magnetic fields at so‐called cyclotron resonance conditions. Previous experimental evidence supports the theory that a resonant interaction between magnetic fields and organisms can exist. This experiment was designed to test one possible site of interaction: channels in the cell membrane. The transport of Ca 2+ ions through the protein channels of the plasma membrane did not show any resonant behavior in the frequency range studied. © 1995 Wiley‐Liss, Inc.
