Abstract A direct search has been made for magnetic monopoles produced in ep collisions at a centre of mass energy of 300 GeV at HERA. The beam pipe surrounding the interaction region during 1995-1997 (integrated luminosity 62 pb^-1) was investigated using a SQUID magnetometer to look for stopped magnetic monopoles. No free magnetic charges were observed and charge-dependent upper limits on the cross section for the electroproduction of magnetic monopoles have been set.
