The susceptibility of A1 is 2 10^-5. The percent increase in the magnetic field when the space within a current carrying toroid to filled with Al is

Question

Accepted Answer

Correct answer: B. (b) Net magnetic field in the toroid filled with Al. B= μH(1+ ) B=B_0(1+ ) Fractional increase in magnetic field. B-B_0B_0= B_0(1+ )-B_0B_0= So, percentage increase in magnetic field B-B_0B_0 100=2 10^-5 10^2=2 10^-3 \%

$The susceptibility of A 1 is 2 \times 10^{- 5} . The percent increase in the magnetic field when the space within a current carrying toroid to filled with Al is$
