Major Distinction from Electrical Dipoles The North pole is analogous to a positive charge and South to a negative charge, in that the field lines flow out from the North pole into the South pole. Since magnets always have two poles, the magnetic field produced is that of a magnetic dipole. Just like with positively and negatively charged ions, like charges repel, and opposite charges attract. This is very similar to an electric dipole, but instead of electrical charges, we have magnetic ones, represented by the North and South poles. These magnets will produce a magnetic field everywhere in space and the force varies only with observation position. Physics students are typically taught about electric dipoles first, and will recognize that many of the properties and formulas resemble each other quite closely, This is because dipoles have the same field shape no matter what field they are influencing and so the same relationships between position and intensity exist with respect to the magnitudes of the charges.Ī common example of a macroscopic magnetic dipole is a common permanent magnet such as a bar magnet. ![]() Dipoles also have a number of properties that shape the natural world in unique ways as the interactions of dipoles often create emergent properties. In such cases it is useful to look a the pair as a single entity as a simplification as it allows us to create simple and commonly applicable equations for them as opposed to considering the two entities as separate. 1.4.2 Observation Location Along Dipole AxisĪ dipole is a pair of field producing entities placed close together to produce a particular pattern of field.1.4.1 Observation Location Perpendicular to Dipole Axis.1.3 Magnetic Dipole Moment and Connection with Torque on a Coil.1.2 Connection With Magnetic Fields in Loops of Wire. ![]() 1.1 Major Distinction from Electrical Dipoles.
