KCET · Physics · Magnetic Effects of Current
The magnetic dipole moment of a current loop is independent of
- A magnetic field in which it is lying
- B number of turns
- C area of the loop
- D current in the loop
Answer & Solution
Correct Answer
(A) magnetic field in which it is lying
Step-by-step Solution
Detailed explanation
Magnetic dipole moment of a current is given by
\(\mathrm{M}=\text { NIA }\)
where \(\mathrm{N}=\) number of turns
\(I=\) current in a loop
\(\mathrm{A}=\) area of the loop
From the above relation it is clear that magnetic dipole moment of a current loop is independent of the magnetic field in which it is lying.
\(\mathrm{M}=\text { NIA }\)
where \(\mathrm{N}=\) number of turns
\(I=\) current in a loop
\(\mathrm{A}=\) area of the loop
From the above relation it is clear that magnetic dipole moment of a current loop is independent of the magnetic field in which it is lying.
