... “Why, yes, Virginia. Physics DOES help us understand some aspects of sex.” … Reproduction in many flower species depends on insects carrying pollen grains from one flower to another. One way honeybees do this is by collecting the grains electrically, because the bees are usually positively charged. ...

Magnetic Interaction
... magnetic interaction There is interaction between a particle and other bodies which depends on the charge of the particle, its position and its velocity (and its spin). We call this interaction a magnetic interaction. Moving charged particles in the body cause the magnetic interaction. ...
