1. A device for collecting semiconductor light emitting diodes, the device comprising:
at least one electromagnet disposed in a fluid chamber into which the semiconductor light emitting diodes are put, the at least one electromagnet comprising a magnetic material configured to form a magnetic field when power is applied;
a power supply coupled to the at least one electromagnet and configured to apply power to the at least one electromagnet; and
a driver configured to move the at least one electromagnet along one or more of a width direction, a longitudinal direction, or a height direction of the fluid chamber,
wherein the at least one electromagnet is configured to guide the semiconductor light emitting devices to a surface at which the magnetic field is formed when power is applied,
wherein the at least one electromagnet comprises:
a first electromagnet disposed adjacent to a bottom surface of the fluid chamber; and
a second electromagnet spaced apart from the first electromagnet by an interval, and
wherein the first electromagnet and the second electromagnet are configured to operate independently.
