In a certain region of empty space, Bz = at (where a is a
1
-
constant with units of N.C¯¹m¯¹), but Bx = By = 0.
(a) What is the magnitude and direction of the electric
curl at that point in terms of a?
(b) Assume that Ẻ always points in the +x direction and
is zero at y = 0. Find Ex as a function of position
and time.
(c) Suppose that a = 1.0 T/s. What is the numerical
rate at which Ex increases or decreases with y at a
given instant of time? Do the units make sense?
