Answer:
A) similar to a bar magnet
Explanation:
As we know that solenoid is similar to a bar magnet and the magnetic field is similar to the bar magnet
So here magnetic field due to a bar magnet is given by
\(B = \mu_0 ni\)
so here one of its end behaves like north pole while other end behaves like a south pole
Here magnetic field is of maximum field strength at the ends of the poles and it is decreasing in similar way as that of bar magnet
So here we can say that correct answer will be
A) similar to a bar magnet
