Problem 15P
long solenoid with radius a and n turns per unit length carries a time-dependent current I (t) in the direction. Find the electric field (magnitude and direction) at a distance s from the axis (both inside and outside the solenoid), in the quasistatic approximation.
ANSWER:
Solution 15P:
Step 1 of 4:-
There is a solenoid with turns per unit length and radius
which carries a time independent current
in the
direction.
We have to find the electric field at a distance from the solenoid axis in the quasistatic approximation, which means that the current through the wire is not changing very rapidly.
We already know the magnetic field inside a solenoid, which is:
It is in the direction of the solenoid axis.
