If magnetic lines are close, then the magnetic field has a lot of magnetic lines of force packed together. This translates into a large number of flux lines per unit of area through which they're passing. A large number of flux lines per unit area means a high field density. High flux density means the magnetic field is strong compared to a field where the flux lines are not as close together.
straight parallel lines
The magnetic field lines are arranged circularly around the wire.
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 stronger the magnetic field is.

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.
Magnetic field is made up of magnetic lines.
The closer the lines of force are together, the stronger the magnetic field it represents.
