straight parallel lines
The magnetic field lines are arranged circularly around the wire.
The list of choices submitted with the question containsno correct description of magnetic field lines.
Magnetic field is made up of magnetic lines.
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
no they are not
The direction of the lines tells us whether there is attraction or repulsion, and the spacing of the lines is a measure of the strength of the magnetic field. The more crowded the lines the stronger the field.
They are called the magnetic field lines.
Magnetic field lines don't cross.
Lines of Force
They are called the magnetic field lines.

The closer the lines the stronger the magnetic field.
