Abstract: A magnet and coil assembly comprises a multi-pole magnetic structure, a coil, an object associated with the coil, and a circuitry for applying a current through the coil. The multi-pole magnetic structure comprises a plurality of magnetic source regions that each extend from a first side of said multi-pole magnetic structure to a second side of said multi-pole magnetic structure and include a first magnetic source region having a first polarity and a second magnetic source region having a second polarity. The multi-pole magnetic structure has a polarity transition region having a polarity transition boundary corresponding to an outer perimeter of the first magnetic source region where a magnetic field measured on the first side or the second side of said multi-pole magnetic field structure transitions from the first polarity to said second polarity. The coil is configured proximate to the first side of said multi-pole magnetic structure and about the polarity transition boundary.

Abstract: Culture systems, devices and related methods and articles may automate the culturing or incubation process according to defined culturing protocols. Such may employ removable multi-well growth cassette. Wells may be subdivided into subwells. Such may employ removable media and waste cartridges and/or gas canisters to supply consumables, which may be supplied in kits, for example with processor executable culturing protocols. Direct fluidic coupling between growth cassettes and the removable cartridges or canisters may be employed. Operational and/or environmental conditions may be sensed or monitored, and may be used to adjust or alter operation. A microscopy subsystem may capture images which may be stored and/or analyzed. Analysis may be used to adjust or alter operation.
