Question
The following questions are based on the animation in the link above.
1. Carefully move the wire loop verticaly up inside the animation box. Be careful not to move it left or right as you are moving upward. What kind of voltage is induced in the wire loop?
Zero
Positive
Negative
2. Explain why this is the case.
3. Carefully move the wire loop verticaly down inside the animation box. Be careful not to move it left or right as you are moving downward. What kind of voltage is induced in the wire loop?
Zero
Positive
Negative
4. Explain why this is the case.
5. Now start with the wire loop on the far right side of the animation box. Slowly and steadily move it horizontally to the left, but do not pass over the green wire. What kind of voltage is induced in the wire loop?
Zero
Positive
Negative
6. Explain why this is the case.
7. Now start with the wire loop just to the right of the green wire. Slowly and steadily move it horizontally to the right. What kind of voltage is induced in the wire loop?
Zero
Positive
Negative
8. Explain why this is the case.
9. Now start with the wire loop on the far left side of the animation. Slowly and steadily move it horizontally all the way to the right side of the animation passing over the green wire. Try to move the wire loop at a constant speed all the way accross. (For this part you may want to start when the voltage starts graphing on the left side and then pause the animation when you are finished, so you can answer the next several questions) What kind of voltage is induced in the wire loop?
Positive, zero, negative
Positive, negative, positive
Negative, positive, negative
Negative, zero, negative
Negative, zero, positive
10. As the loop approaches the green wire, but before it crosses over it, what happens to the induced voltage?
It remains zero
It remains a constant non-zero value
It increases linearly
In increases exponentially
11. What direction is the magnetic field produced by the green wire pointing in the region to the right of the green wire?
Up
Down
Left
right
Into the screen
Out of the screen
12. Explain how you calculated the above answer.
13. What direction is the magnetic field produced by the green wire pointing in the region to the left of the green wire?
Up
Down
Left
right
Into the screen
Out of the screen
14. Explain how you calculated the above answer.
15. Which direction is the current in the green wire flowing?
Up
Down
16. Explain how you calculated the above answer.
Explanation / Answer
1 ) voltage is induced in the wire loop - zero .
2) As, there is no change in magnetic flux .
3) voltage is induced in the wire loop - zero .
4) As, there is no change in magnetic flux .
5) voltage is induced in the wire loop - negative
6) As, the magnetic flux is decreasing .
7) voltage is induced in the wire loop - positive
8) As, the magnetic flux is increasing .
9) voltage is induced in the wire loop - Negative, zero, positive
10) induced voltage - It increases exponentially
11) direction is the magnetic field produced by the green - Into the screen
12) By right hand rule direction of magnetic field is Into the screen .
13) direction is the magnetic field produced by the green wire - Out of the screen
14) By right hand rule direction of magnetic field is out of the screen .
15) current in the green wire flowing - Up
16) By right hand rule direction of current is in upwards direction .
