Q-00019642
What would happen to the magnetic field if a current-carrying conductor is shaped into a loop?
1
The field remains uniform
2
The field strengthens at the center of the loop
3
The field disappears
4
The field is directed radially outward
Answer and Solution
Answer
B. The field strengthens at the center of the loop
Solution:
Shaping a current-carrying conductor into a loop concentrates the magnetic field lines inside the loop, significantly increasing the field strength at the center compared to a straight wire.
