PURPOSE: A sample holder and a free fall testing device having the same is provided to minimize the influence of the residual magnetic force and reduce the interference with respect to a separation of a sample while a free falling of the sample. CONSTITUTION: A sample holder(200) comprises an armature(210), a housing(220), a link unit(223), a male coupler(240), and a connection member(250). The housing comprises a groove containing the armature and a coil(221) is embedded inside. One end part of the link unit is joined to the housing and the other end part is joined to a female coupler(230). One side of the male coupler is contacted to the female coupler and the other end part of the male coupler is contacted to a sample(300). The male coupler falls down with the sample when the power is supplied to the coil. One end part of the connection member is joined to the armature and the other end part is joined to the outer circumference of the female coupler. |
