Direct current and alternating current
It is an alternating current that switches its polarity 60 times in a second. 60 Hertz is the frequency that electricity is generated in the U.S.
Thomas Edison believed it was dangerous to fool around with alternating currents and promoted the use of direct current instead. He was in a bitter rivalry with Nikola Tesla, who championed the use of alternating current for its efficiency over long distances.

A changing magnetic field generates an electric field and alternating currents are accompanied (or caused) by alternating voltages.
