What is the magnitude of the magnetic flux for a loop of wire if the following is true? Radius = 0.3 m Plane of the loop: x/y plane Uniform B-field (2.0 T) passing through loop at right angles to the plane of the loop acting along the -z axis.
a. The flux is 0.19 Wb
b. The flux is 0.28 Wb
c. The flux is 0.43 Wb
d. The flux is 0.56 Wb
If the loop in question #17 rotated such that the plane of the loop was halfway between its initial position and a position wherein the plane of the loop was in the y/z plane, determine the flux?
a. 0.40 Wb
b. 0.59 Wb
c. 0.71 Wb
d. 0.37 Wb
A loop of wire (Area of loop = 0.02 m2, plane of loop in x/y plane) enters a region of space with a uniform B-field (100 T) oriented in the positive z direction. What is the induced emf for the loop as it traverses the field?
a. 2 v
b. 0.2 v
c. 0.001 v
d. 0 v
Lenz’s Law can be interpreted as meaning:
