EMI Mr. Weinberg, I DID need to know that....

Question 2:
Magnetic field describes how the influence of magnetic force is transmitted through space. Magnetic force describes how magnetic flux passes through a specific region of space, specifically a loop or area through which magnetic field lines travel. It is possible to have magnetic field and not have magnetic flux (if area = 0 or if the angle between B and the normal vector is 90 degrees), but it is not possible to have magnetic flux without magnetic field.

Problems:
2. 0.147 Volts

10.
a) 0.169 Volts

12.
b) 4.29 x 10^-2 Volts
c) 17.2 mA

13.
a) .841 m/s
b) .757 N/C

89. 7.27 x 10^-3 J

Here are a couple of sites with fun EMI tools to play with:
