A conducting loop of wire is placed in a magnetic field that is normal to the plane of the loop. Which one of the following actions will not result in an induced current in the loop?
1)Decrease the area of the loop.
2)Increase the strength of the magnetic field.
3)Decrease the strength of the magnetic field.
4)Rotate the loop about an axis that is parallel to the field and passes through the center of the loop.
5)Rotate the loop about an axis that is perpendicular to the field and passes through the center of the loop.
-------------------------------------------
Now, I know the basics of magnetic fields- as long as there is relative motion between a magnet and a loop there will be current in the loop. But I am having issues with this question. Is changing the size of a loop "relative motion"?
Thanks for your help.
