Distance between exposed object and exposure source
The coil was lowered into the incubation chamber which was movable to get the desired MF at the location of the sample. The adherent cells on a glass cover slip were positioned 2 mm below the coil. For sham control, the current was passed into the two coil windings in opposite directions to obtain zero MF at the same time producing the same heat (37°C) as exposure experiments.
