AA dipole with a north and a south pole
BAn isolated north pole with no partner
CAn isolated south pole with no partner
DA pole-free field of uniform strength
Answer & Solution
Correct answer: A. A dipole with a north and a south pole
1. A current loop always produces a magnetic dipole.
2. A dipole is a field that acts like a north pole and south pole pair.
3. Since every magnetic effect is traced back to current loops, isolated poles never appear.
4. An isolated pole would be a magnetic monopole, and none has ever been observed.
