Homework Statement
The figure shows a ring of copper with its plane perpendicular to the axis of the nearby rod-shaped magnet. For each of the situations described below, indicate whether there will or will not be a current induced in the ring and justify your reasoning, drawing pictures if necessary.
The magnet is moved horizontally toward the left?
The ring is moved away from the magnet?
The ring is rotated around any of its diameters?
The magnet is moved up or down?
The ring is rotated around its center in the plane in which it lies?
Homework Equations
ΔFlux=Induced Current
The Attempt at a Solution
The magnet is moved horizontally toward the left?
Yes, there will be a change in flux so a current will be induced.
The ring is moved away from the magnet?
Yes, there will be a change in flux so a current will be induced.
The ring is rotated around any of its diameters?
No, there would not be a change in flux so no current will be induced.
The magnet is moved up or down?
No, there would not be a change in flux so no current will be induced.
The ring is rotated around its center in the plane in which it lies?
Yes, there will be a change in flux similar to if the magnet rotated, therefore a current will be induced.
Im not sure how correct my reasoning or answers are, any explanation or help would be much appreciated. Thank you
