Answer 1

Option D is correct

Answer 2

Answer:

(D) The intensity of magnetic field in A is less than in B

Explanation:

The resistor combination is circuit A is series thus making the equivalent resistance (R1+R2) higher than that in circuit B in which the combination is parallel ( (R1*R2)/(R1+R2) ). Since, higher the resistance with the same voltage(here 5 V), lower the current. More current will flow in the circuit B.

Also, the intensity of magnetic field is directly proportional to the current flowing through the wire.

Hence, The intensity of magnetic field in A is less than in B.
