Abstract
There are provided a linear motor and the linear compressor using the linear motor. The linear motor includes a bobbin, a coil wound in the bobbin, an outer core provided on the bobbin, an inner core provided to perform a linear reciprocating motion with a moving body, and a magnet provided on the inner core so that the inner core and the moving body perform a linear reciprocating motion. The magnet is configured to provide a gap between the magnet and an outer core and to be in close contact to the inner core.
