If particles undergo uniform circular motion while they remain in a magnetic field, how are the particles ever able to escape? or move through the field?

Draw a magnetic field and draw a particle moving into it - it will then undergo circular motion so it's initial velocity was tangent to the circle. Right? If it's moving too fast, the circle will be larger and it will end up exiting the magnetic field before it can make a full loop.
