Assignment 2
Problem 1
a) The figure shows a long wire with a changing current that increases over time (
I (t)
dI
> 0). Indicate the direction of the magnetic field on the plane of the figure. Give a
well-reasoned response on whether the induced current in the nearby circuit is
dt
clockwise or counterclockwise. (10 points)
Figure 1:
Figure 2:
, Figure 3:
The magnetic field is directed out of the plane, shown in Figure 2. As the current increases
so does the magnetic flux. By following Lenz's Law we see that an increasing upward flux
through a circuit induces a downward magneticfield, in the opposite direction, to oppose the
flux change. By using the right hand rule we can see that to produce this induced field, the
