GEOLOGY

Detailed explanation-1: -Magnetic field lines give the direction of magnetic field around a conductor. So the pattern of field lines is similar to concentric circles. It resembles the pattern formed by iron filings around the conductor.

Detailed explanation-2: -the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field. the lines have arrowheads to show the direction of the force exerted by a magnetic north pole. the arrowheads point from the north pole of the magnet to its south pole.

Detailed explanation-3: -The magnetic field lines show the direction in which the magnetic force is acting at any particular point. The density of the magnetic field lines shows the strength of the magnetic force acting. If the lines are close together the magnetic force is great, if the lines are spread out the force is weak.

Detailed explanation-4: -A shape field is transparent, or unfilled, if its BgPattern property is set to FP CLEAR; otherwise, the field is filled. When a shape is unfilled, any shapes on the layers beneath it show through. A filled shape is opaque and covers any shapes below it.

Detailed explanation-5: -place the plotting compass near the magnet on a piece of paper. mark the direction the compass needle points. move the plotting compass to many different positions in the magnetic field, marking the needle direction each time. More items
