磁场与磁通量Magnetic Forces And Magnetic Fields.
antiferromagnetism- magnetic field creates parallel but opposing spins; varies with temperature diamagnetism- phenomenon exhibited by materials like copper or bismuth that become magnetized in a magnetic field with a polarity opposite to the magnetic force; unlike iron they are slightly repelled by a ma...
magnetic field n. A condition found in the region around a magnet or an electric current, characterized by the existence of a detectable magnetic force at every point in the region and by the existence of magnetic poles. American Heritage® Dictionary of the English Language, Fifth Edition. ...
Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other. From this point of ...
Magnetic field of steady currents Magnetic forces Lorentz force Repulsion or attraction between two magnetic dipoles Magnetization effects in matter Magnetic properties of matter Induced and permanent atomic magnetic dipoles Diamagnetism Paramagnetism Ferromagnetism Role of exchange interaction Remanence Antiferroma...
Learn the magnetic force formula, learn how to determine the magnetic force direction, understand the magnetic field equations, and discover the relationship between a magnetic field and an electric current. Updated: 11/21/2023 Table of Contents Magnetic Force Formula Magnetic Field Equation The ...
Equally strange, the strength of the exerted force depends upon the direction of the charge's motion. This peculiar behavior reveals the presence of a magnetic field .These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as ...
Magnets not only exert a force on one another, they also can exert a twisting moment as well. If you have a single magnet in free space, the magnetic field looks something like the image at left. The color is related to the strength of the magnetic field, while the black lines of ...
Magnetic field The magnetic field of a bar magnet is strongest at the poles. Permanent magnets vs Electromagnets retains a magnetic force Can not be turned on and off Electromagnets Use electricity to create a magnetic field They can be controlled (turned on and off) Their force or strength of...
Understand what a magnetic field is. Learn the definition of magnetic field lines and understand how one can detect magnetic field lines using a...
