What type of magnetic field lines represent uniform magnetic field?
straight parallel lines
A current in a long straight wire produces a magnetic field. These magnetic field lines?
The magnetic field lines are arranged circularly around the wire.
What is a magnetic field made up of?
Magnetic field is made up of magnetic lines.
Where is the magnetic force the greatest on a magnet?
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.
How tightly packed the magnetic lines tells us?
The closer the magnetic field lines, the stronger the magnetic force in that area.
What are the lines called that map out the magnetic field around magnetic?
They are called the magnetic field lines.
Where do magnetic field lines cross?
Magnetic field lines don't cross.
A magnetic field is described by magnetic lines of?
Lines of Force

What does the relative density of lines of a magnetic field tell us about the strength of the field?
The closer the lines the stronger the magnetic field.

Magnetic field is made up of magnetic lines.

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.
Do magnetic field lines close together indicate a weaker magnetic field?
no they are not
How could straight copper wire produce magnetic field lines?
The copper by itself will do nothing of the sort. It will be surrounded by magnetic field lines if a current flows through it. It is the current that produces the magnetic field lines.
What best describes magnetic field lines?
Magnetic fields are produced because of moving electric charges, and visualizing the very complex mathematical relationships that fall under the magnetic field might become much easier if magnetic field lines were used. A higher density of field lines means a stronger magnetic field. Keep in mind that those lines do not actually exist; they are drawn only to visualize the strength of the magnetic field.
