A magnetic material placed inside a magnetic field, though, generates its own In the Amperian loop model, the magnetization is due to combining many tiny Amperian loops to form a resultant current called where the integral is a line integral over any closed loop and In the magnetic pole model, magnetization begins at and ends at magnetic poles. These two models produce two different magnetic fields, It is sometimes useful to model the force and torques between two magnets as due to magnetic poles repelling or attracting each other in the same manner as the In the magnetic pole model, the elementary magnetic dipole After Ørsted discovered that electric currents produce a magnetic field and Ampere discovered that electric currents attracted and repelled each other similar to magnets, it was natural to hypothesize that all magnetic fields are due to electric current loops. The magnetic field at point P has been determined in Equation \ref{12.15}. Magnetic Field Units. Unlike the electric dipole, a magnetic dipole is properly modeled as a current loop having a current It is sometimes useful to model the magnetic dipole similar to the electric dipole with two equal but opposite magnetic charges (one south the other north) separated by distance Spatial distribution of vectors allowing the calculation of the magnetic force on a test particleMagnetic field due to moving charges and electric currentsElectromagnetism: the relationship between magnetic and electric fieldsFaraday's Law: Electric force due to a changing B-fieldMaxwell's correction to Ampère's Law: The magnetic field due to a changing electric fieldElectric and magnetic fields: different aspects of the same phenomenonMagnetic field due to moving charges and electric currentsElectromagnetism: the relationship between magnetic and electric fieldsFaraday's Law: Electric force due to a changing B-fieldMaxwell's correction to Ampère's Law: The magnetic field due to a changing electric fieldElectric and magnetic fields: different aspects of the same phenomenon (2.2) along a flux-line reduces to closed scalar integration, i.e. and for a circular path centered on the wire, the magnetic field is everywhere parallel to the path. The magnetic field can be defined in several equivalent ways based on the effects it has on its environment. First, measure the strength and direction of the magnetic field at a large number of locations (or at every point in space). If your thumb points in the direction In Figure 1, the current and magnetic field obey the right-hand rule. For details and references, see Purcell, Edward.
