Write the correct option by observing the figures.(a) Magnetic field in A is stronger. (b) Magnetic field in B is stronger. (c) Magnetic fields in A and B are same. (d) Magnetic fields in A and B are weaker.

Answer»

(b) Magnetic field in B is stronger.

[Explanation : The resistance in circuit B is less (parallel combination) than that in A. Hence, the current in B is more than that in A. Therefore, the magnetic field in B is stronger than that in A.]
