A solenoid has a circular cross section with a radius of R=0.05 m, and has a turn density of n =1600 turns/m. The current flowing through the solenoid is 1+0.6*t A/s. (a) What is the magnitude of the rate of increase of the magnetic field (dB/dt) inside the solenoid? T/s (b) What is the magnitude of the induced electric field at a distance 7\" = 0.025 m away from the center of the solenoid? N/ C (c) What is the magnitude of the induced electric field at a distance 7' = 0.05 m away from the center of the solenoid? N/C (d) What is the magnitude of the induced electric field at a distance 7 : 0.085 m away from the center of the solenoid? N / C
