SUMMARY
The discussion focuses on calculating the magnitude of the induced electromotive force (emf) in a current loop with a radius of 2 cm, transitioning from an angle of 11 degrees to 66 degrees in a magnetic field of 2 T over 0.5 seconds. The relevant equations include the flux change formula E = ΔΦ/Δt, where ΔΦ is the change in magnetic flux. Additionally, the induced current is determined using the wire's resistivity of 1.71 x 10-8 Ωm and thickness of 1.04 mm, with calculations required to find the induced current to the nearest tenth of a milliamp.
