Homework Statement
In the central region of a solenoid that is connected to a radio frequency power source, the magnetic field oscillates at 2.5·10^6 cycles per second with an amplitude of 4 gauss. What is the amplitude of the oscillating electric field at a point 3 cm from the axis? (This point lies within the region where the magnetic field is nearly uniform.)
Homework Equations
∇ × E = −∂B/∂t (maybe)
The Attempt at a Solution
[/B]
I could only find one equation relating the electric field to the magnetic field in my book. I’m not sure if it’s right or not.
∇ × E = −∂B/∂t
I’m not really sure where to go from here. I’m guessing I have the wrong equation, but I’m not quite sure since I haven’t taken calc 3 and am not very familiar with partial differentiation or gradients.
