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.

A

If both statement 1 and statement 2 are ture, statement 2 is the correct explanation of statement 1.

B

If both statement 1 and statement 2 are ture, statement 2 is not the correct explanation of statement 1.

C

If statement 1 is true, statement 2 is false.

D

If statement 1 is false, statement 2 is true.

Text Solution

Verified by Experts

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