The figure below shows two circular regions R₁ and R₂ with radii r₁ = 20.3 cm and r₂ = 31.0 cm. In R₁ there is a uniform magnetic field of magnitude B₁ = 50.0 mT directed into the page, and in R₂ there is a uniform magnetic field of magnitude B₂ = 75.9 mT directed out of the page (ignore fringing). Both fields are decreasing at the rate of 8.70 mT/s. Calculate efE · d´3² for (a) path 1, (b) path 2, and (c) path 3. -Path 3, -Path 1 (a) Number i -1.16 (b) Number i -2.71 (c) Number i 1.55 Units mV Units mV Units mV Path 2 +
A long solenoid has a diameter of 17.9 cm. When a current i exists in its windings, a uniform magnetic field of magnitude B = 42.5 mT is produced in its interior. By decreasing i, the field is caused to decrease at the rate of 7.01 mT/s. Calculate the magnitude of the induced electric field (a) 7.15 cm and (b) 16.0 cm from the axis of the solenoid. (a) Number 2.5060e-4 Units V/m (b) Number i 17.55 Units V/m P
