Los investigadores desarrollaron nuevos metamateriales giromagnéticos con propiedades de doble índice cero y características no recíprocas. Estos materiales permiten la generación determinista de pulsos de vórtice espacio-temporal ultrarrobustos mediante el anclaje de singularidades a las transiciones de fase topológicas.

Magnetic Field due to Moving Charges 01:23

8.2K

A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...

Magnetostatic Boundary Conditions 01:28

An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...

Divergence and Curl of Magnetic Field 01:26

The magnetic field due to a volume current distribution given by the Biot–Savart Law can be expressed as follows:

To evaluate the divergence of the magnetic field, the divergence is applied to both sides of the Biot–Savart equation:

Applying the vector product rule, the term within the integral is simplified to the following equation:

The first term involving the curl of the current density function is zero since the current density is independent of the field coordinates. Using...

Magnetic Vector Potential 01:15

In electrostatics, the electric field can be written as the negative gradient of the potential. In magnetostatics, the zero divergence of the magnetic field ensures that the magnetic field can be expressed as the curl of a vector potential. This potential is known as the magnetic vector potential.
Consider an ideal solenoid with n turns per unit length and radius R. If I is the current through the solenoid, the magnetic field inside the solenoid is expressed as the product of vacuum...

Magnetic Field Lines 01:19

4.0K

The representation of magnetic fields by magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. Each of the magnetic field lines forms a closed loop. The field lines emerge from the north pole (N), loop around to the south pole (S), and continue through the bar magnet back to the north pole.
Magnetic field lines follow several hard-and-fast rules:

The direction of the magnetic field is tangent to the field line at any point in space. A small...

Atomic Nuclei: Nuclear Relaxation Processes 01:23

594

In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis,  the precessing magnetic moments are randomly oriented around the z-axis.
