Question

what happen to the strength of magnetic field if the no. of tonnes is increased ?​

Answer 1

if you increase the no of turns by n times then magnetic field will also increase by n times

as no of turns is directly proposnal to the magnetic field

as B=nu(not)nI

Answer 2

the strength of magnetic field increases n times if the turns are increased by n

it means strength of magnetic field in directly proportional to the turns.

hope it helps
