A wireline coupler that connects a first data wireline to a second data wireline comprises: a first housing that is attached to the first data wireline, wherein the first housing comprises an electromagnet; a second housing that is attached to the second data wireline, wherein the second housing comprises a metal; wherein the electromagnet forms a magnetic field when electrical data flows in the first wireline, and wherein the magnetic field attracts the metal of the second housing and causes the first housing to connect with the second housing, such that first data wireline is operationally connected with the second data wireline.
