If someone has to find the direction of the magnetic field lines, they would have to keep a compass near it, then it's north pole would show the direction.

Thank you. If u have further inquiries feel free to ask me.

I hope u will follow me and make this the brainliest.

The best description of a magnetic field line is option D. A magnetic field line shows the direction a compass needle would point.

What are the magnetic field lines?

Magnetic field traces are the strains in a magnetic discipline the tangent of which at any factor will give the sector route at that point and its density offers the value of the sphere.
few properties of magnetic field lines:-

⇒ Magnetic subject traces do not intersect each other.

⇒ They emerge from the north pole and merge/end at the south pole.

⇒ They flow from the north pole to the south pole outdoor the fabric and from the south pole to the north pole within a material.

⇒these lines formed are cl

osed curves.
