Statement 1: When radius of a circular loop carrying current is doubled, its magnetic moment becomes four times.
Statement 2: Magnetic moment depends on the area of the loop.

Text Solution

Verified by Experts

The correct Answer is:
`A`
Initially moment `M= I =pi r^(2)`
And afterwards `M' =I pi (2r)^(2) = 4I (pir^(2)) =4M`
So magnetic moment becomes four times when radius is doubled .
