A) \[0.1\,\,A-{{m}^{2}}\]
B) \[0.01\,\,A-{{m}^{2}}\]
C) \[0.2\,\,A-{{m}^{2}}\]
D) \[1.2\,\,A-{{m}^{2}}\]
Correct Answer: A
Solution :
Key Idea: Circumference of a circle of radius r is \[2\,\pi r\]. Magnetic moment (M) is a measure of the strength of a magnetic source. It is denned as pole strength (m) multiplied by distance (d) \[M=md\]You need to login to perform this action.
