Homework Statement
A parallel plate capacitor has circular plates of radius 12.0 cm that are separated by a distance of 4.0 mm. The potential across the capacitor is increased at a constant rate of 1300 V/s. Determine the magnitude of the magnetic field between the plates at a distance r = 3.0 cm from the center.
Homework Equations
id = ε0A(dE/dt)
B = [μ0id/(2∏R2)]r
The Attempt at a Solution
id = ε0A(dE/dt)
dE/dt = 1300 V/s
A = ∏R2
R = 0.12 m
ε0 = 8.85E-12
id = 5.2E-10
B = [μ0id/(2∏R2)]r
r = 0.03 m
R = 0.12 m
id = 5.2E-10
μ0 = 1.26E-6
B = 2.17E-16
Correct answer is 3.39E-15
How do I get there?
