Web28 dec. 2024 · Magnetic fields describe how the magnetic force is distributed through space around objects. Generally, for an object that's magnetic, the magnetic field lines travel from the object's north pole to the south pole, just as they do for the Earth's magnetic field, as shown in the diagram above. Web16 mrt. 2024 · the field lines are more concentrated at the poles The magnetic field is strongest at the poles, where the field lines are most concentrated. Two bar magnets … WebFigure 22.15 Small compasses could be used to map the fields shown here. (a) The magnetic field of a circular current loop is similar to that of a bar magnet. (b) A long and straight wire creates a field with magnetic field lines forming circular loops.
