1. A cartridge for a vaporizer device, the cartridge comprising:
a first storage chamber and a second storage chamber, the first storage chamber being configured to hold a first fraction of a vaporizable material and the second storage chamber being configured to hold a second fraction of the vaporizable material;
an elongate member that is in fluid communication with the first storage chamber and the second storage chamber, the elongate member having a channel extending therethrough, the elongate member being configured to receive the vaporizable material; and
a magnetic element disposed within the channel of the elongate member, the magnetic element being configured to selectively oscillate between a first position and a second position so as to substantially control the flow of the vaporizable material into the elongate member.
