A new method of spatial confinement of ultra cold neutrons completely isolated from the wall is proposed. Neutrons are trapped in a reversed-field-pinch magnetic configuration by the interaction between the neutron magnetic dipole moment and the magnetic field. The reversed-field-pinch device ZT-H is adopted as parametric example to study the feasibility of present scheme. DeBroglie wave lengths of the trapped neutrons are longer than about 790 Angstrom and much longer than those attainable using the conventional cold neutron moderator. Average collision time of neutrons with ions is longer than 6,800s in argon plasma with electron and ion temperature of 8ke V, electron density of 1.5 x 10^<20>m^<-3>, and Z_<eff> of 17. Since neutron life time is shorter than the collision time, neutrons are collision free in the magnetic trap.
