Lines of the magnetic field produced by a long straight wire carrying a current are:A.radially inward toward the wireB.radially outward from the wireC.circles that are concentric with the wireD.in the direction of the current的答案是什么.用刷刷题APP,拍照
Magnetic fields arise from charges, similar to electric fields, but are different in that the charges must be moving. A long straight wire carrying a current is the simplest example of a moving charge that generates a magnetic field. The force a charge feels when moving through a magnetic ...
Hence magnetic field at point O= Khimraj Last Activity: 6 Years ago Magnetic field due to a wire of finite length is given by B = (uoI/4 r)(sin + sin ) where is angle QOM and is angle POM r is perpendicular distance So B = (uoI/4 ...
Determining the Current in a Wire from a Plot of the Magnetic Field as a Function of Radius Using the Principle of Superposition to Determine the Magnitude of a Magnetic Field at Some Point Near Several Long Straight Current-Carrying Wires Determining if Two Adjacent Current...
Force on a Wire in a Magnetic Field, Nature 246, 208 - Lowes - 1973 () Citation Context ... can be calculated via the interaction of the current and magnetization in the wire with only the fields present before the wire was added to the problem, as emphasized in sec. 35 of [18] ...
For an experiment on the magnetic field around a current - carrying wire, what is the correct order of operations? First: A. 和三响自象万门间给厂强设身须把界什和三响自象万门间给厂强设身须把界什Connect the power supply和三响自象万门间给厂强设身须把界什和三响自象万门间给厂强设身须...
21An electric current flowing through a wire produces a magnetic field around the wire. Four wires carrying identical currents are shown placed at the corners of a square. Each wire produces a field of flux density B at the centre of the square.The symbol ④ indicates a current flowing ...
