Question

write the correct options by observing the figures

Answer 1

i think option a) is the right answer

Answer 2

Answer: Magnetic field in B is stronger

Explanation:

Magnetic field due to a loop increases with the amount of current in the wire.

In A, one resistance is present in the circuit having value R.

In B, two resistors are connected in parallel to the circuit. The equivalent resistance, would be R/2.

R = (R×R)/(R+R) = R /2

Thus, the resistance is less in B so, more current would flow. With more amount of current, the strength of the magnetic field would increase in B.
