List the ways in which magnetic field lines and electric field lines are similar. For example, the field direction is tangent to the line at any point in space. Also list the ways in which they differ. For example, electric force is parallel to electric field lines, whereas magnetic force on moving charges is perpendicular to magnetic field lines.

The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field.

• Two charges, negative and positive, form electric field lines; two poles, north, and south, produce magnetic field lines.
• In the same way that similar charges repel and unlike charges attract in an electric field, comparable poles repel and unlike poles attract in a magnetic field.
• The magnetic and electric field lines in space are perpendicular to each other.

• Magnetic force is perpendicular to the magnetic field line, whereas electric force is parallel to the electric field lines.
• Magnetic field lines are continuous loops, whereas electric lines have specific beginning and ending locations.
• The positive and negative charge is distinct entities in electric field lines, whereas the South and North Poles of a magnet cannot be distinguished.
