An inductor, also called a coil or reactor, is a passive two-terminal electrical component that stores electrical energy in a magnetic field when electric current is flowing through it. An inductor typically consists of an electric conductor, such as a wire, that is wound into a coil. When the current flowing through an inductor changes, the time-varying magnetic field induces a voltage in the conductor, described by Faraday's law of induction. According to Lenz's law, the direction of induced electromotive force (e.m.f.) opposes the change in current that created it.
Designated a National Historic Landmark in 1963, the park is currently managed by the Central Park Conservancy under contract with the city government. The Conservancy is a nonprofit organization that contributes 85% of Central Park's $25 million dollar annual budget, and employs 80% of the park's maintenance staff.
For more than 150 years, visitors have flocked to Central Park's 843 green... For more than 150 years, visitors have flocked to Central Park's 843 green acres in the heart of Manhattan. Since 1980, the Park has been managed by the Central Park Conservancy, in partnership with the public. Central Park is open 6 am to 1 am daily.
