The magnetic field in 1a increases uniformly from 0 to 1.5 t in 10 s. the circular loop of copper wire (rhocu = 1.7×10−8 ωm) has a radius of 0.1 m and the wire itself has a radius of 0.001 m. determine the total charge that passes by a point in the wire during that 10 s. would your answer change if it took 20 s to change from 0 to 1.5 t instead? explain in words.
