The new D25 Alpha BI Coil, historically a Magstim Innovations product, now features as part of the main coil range at Magstim due to popular request. The magnetic field of this coil is very focal and shallow, which is ideal for rodent-subject research. The branding iron (BI) design of this coil moves the handle away from the stimulation site, offering a practical solution for stimulating small, confined targets. The coil is compatible with Magstim Rapid2 stimulators.
