Bursts of magnetic fields induce jumps of misdirection in bees by a mechanism of magnetic resonance

Magnetic field (MF) bursts at a frequency of 250 Hz oriented parallel to the field-lines of the EMF induce unequivocal ‘jumps’ of misdirection of up to +10°. The regression of burst intensity (BI inγ; for a range of 10–1400γ) and the size of the induced jumps of misdirection (DMID in angular degrees) follow the equation: DMID= −1+ln BI. Compensation (<5% of the total intensity) of the EMF, continuous 250 Hz fields and bursts perpendicular to the static MF have no effect. The effects described are discussed from the point of view of magnetic resonance.
