Mapping Of Magnetic Lines Of Force Elementary Science Youtube To draw the lines of force of combined magnetic field due to the bar magnet and the earth’s magnetic field and locate the null points. hence the pole strengt. 20.6. this equation gives the force on a straight current carrying wire of length ℓ in a magnetic field of strength b. the angle θ is the angle between the current vector and the magnetic field vector. note that ℓ is the length of wire that is in the magnetic field and for which θ ≠ 0, as shown in figure 20.19.

The magnetic field is traditionally called the b field. figure 22.3.1 22.3. 1: magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) if small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the. In a rod shaped piece of iron, the atoms will tend to line up so that all the north poles face one end of the rod and all the south poles face the other end. since iron filings are rod shaped, the atoms line up pointing along the length of the rod, and the rods line up parallel to the direction of the applied magnetic field. The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. magnetic field lines are a visual tool used to represent magnetic fields. they describe the direction of the magnetic force on a north monopole at any given position. because monopoles are not found to exist in nature, we also discuss alternate means to describe the field lines in the sections.
