Lecture 15 Outline of Last Lecture II. Induced Current a. When a conductive object (metal bar, wire, etc.) moves through a magnetic field B, a current is induced in the direction of the magnetic force FB. b. Metal bar through a magnetic field c. Bar magnet through a coiled conductive wire d. Closed loop inside a circuit III. Magnetic Flux (ΦB) a. ΦB = ΣBΔAcosθ in T/m2(weber, Wb) b. Change in magnetic flux causes an induced current i. Can be due to change in magnetic field strength (B), area (A), or angle (θ) PHYS 012 1st Edition
