Dear John,

I am not sure I understand your question. Are you asking if, when one 
shoots a charged particle into a region with a magnetic field, the 
radius of circle described by the motion of the particle perpendicular 
to its original motion can increase exponentially, the answer is 
certainly yes. 

Recall that the formula for determining this radius is inversely 
proportional to both the strength of the magnetic field and the velocity 
of the particle. If either of them changes expoentially, then yes, 
certainly, the radius in question will change exponentially.

I hope this answers your question!
