A single loop of copper wire, lying flat in a plane, has an area of 8.40 cm² and a resistance of 1.80 . A uniform magnetic field points perpendicular to the plane of the loop. The field initially has a magnitude of 0.500 T, and the magnitude increases linearly to 2.00 T in a time of 1.08 s. What is the induced current (in mA) in the loop of wire over this time? mA

Suppose a conducting rod is 94.5 cm long and slides on a pair of rails at 2.5 m/s. Part (a) What is the strength of the magnetic field in T if a 2 V emf is induced?

μ_0 = 4π×10^(−7) T.m/A

c. What is the resistance of the coil given that the diameter of the wire is 2.00 mm? (Recall, resistance of wire is given by R = ρL/A, where ρ is the resistivity of the metal, L is the length of the wire, and A is the cross-sectional area.)
