B) A magnetic field is created around the wire.

This idea is one of the fundamental ideas of physics - an electric current has a magnetic field, whether it's moving through a wire or space.

Answer:

B. A magnetic field

Explanation:

As per Oersted experimental study he observed that when a magnetic needle is placed around the wire then this magnetic needle will show the deflection

this deflection is due to magnetic force due to some external magnetic field

So when we place a current carrying wire near the magnetic needle then it will produce the magnetic field near the wire and hence it will show the deflection in it

so here we can say that current carrying wire will produce magnetic field in the region surrounding the wire

so correct answer will be

B. A magnetic field
