Answer 1

Option: C .... is correct...

strength of magnetic field ...

B = uNi .....

where, u - Permeability
N - no of turns per unit length
i - current through the wire...


so, magnetic field depends on no of turns and current in the turns ..

in Set-up:X, no of cells is more than in Set-up:Y. so, the current in X is more than in Y. so, magnetic field is more.

No of turns in X is more than in Y, so no of turns per unit length in X is more than Y. So, field strength is more in X than Y.
