Homework Statement
The magnetic field inside a 4.0-cm-diameter superconducting solenoid varies sinusoidally between 8.0 T and 12.0 T at a frequency of 10 Hz.
Pt. 1--> What is the maximum electric field strength at a point 1.5 cm from the solenoid
axis?
Ans.- -> 0.942 V/m
Pt. 2--> What is the value of B at the instant E reaches its maximum value?
Homework Equations
E=cB
The Attempt at a Solution
.942/c=3.14*10^-9
Which is the wrong answer. I can't find any other relationships between E and B! Help please!
