Unformatted text preview: discussed later). tsl250 – p.1/2 Lenz’s Law (2) In the situation shown below the current induced in the conducting ring generates a magnetic field whose flux counteracts the change in magnetic flux caused by the bar magnet. • Moving the bar magnet closer to the ring increases the magnetic field ~ B 1 (solid field lines) through the ring by the amount Δ ~ B 1 . • The resultant change in magnetic flux through the ring induces a current I in the direction shown. • The induced current I , in turn, generates a magnetic field ~ B 2 (dashed field lines) in a direction that opposes the change of flux caused by the moving bar magnet. tsl251 – p.2/2...
