Abstract
Analytic expressions of a magnetic multipole field generated by a row of permanent magnets which are arranged on a same plane have been obtained. Each magnet is replaced by two sheet currents flowing in opposite directions through each side of the magnet. The results have been compared with measured values and both have been in good agreement. These expressions are simple and very convenient for design of a plasma source surrounded by magnetic multipole fields.Keywords
