AP EAMCET · PHYSICS · Magnetic Effects of Current
A wire loop of irregular shape carrying current is placed in an external magnetic field. If the wire is flexible, the shape of the loop changes to
- A helical
- B circular
- C straight line
- D parabolic
Answer & Solution
Correct Answer
(B) circular
Step-by-step Solution
Detailed explanation
A loop of irregular shape carrying current when placed in an external magnetic field, it assume circular shape with its plane normal to the field in order to maximum magnetic flux link with loop. This is because for a given perimeter circular encloses maximum area than any other…
