The magnetic field around a straight current - carrying wire is in the shape of _. A. circles B. squares C. triangles D. rectangles 相关知识点: 试题来源: 解析 A。解析:载流直导线周围的磁场形状是圆形的。B、C、D选项中的形状不符合载流直导线周围磁场的形状特征。
The magnetic field has direction as it is a vector quantity. For conventional current flowing through a straight wire, this can be found by theright-hand rule. Imagine gripping your right hand around the wire with your thumb pointing in the current direction to use this rule. The fingers sho...
Near the Wire: The magnetic field is most intense close to the carrying conductor. Here, the field lines are densely packed, indicating a stronger magnetic effect. Away from the Wire: As one moves further from the wire, the magnetic field’s intensity diminishes. This decrease in strength is...

A magnetic field is avector, which means it has magnitude and direction. Ifelectric currentflows in a straight line, the right hand rule shows the direction invisible magnetic field lines flow around a wire. If you imagine gripping the wire with your right hand with your thumb pointing in th...
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 ...
In order to compare our reconstruction to the expected resulting field from a current carrying solenoid, a calculation of the 3D magnetic field was done by dividing a description of the solenoid into 0.1 mm long straight wire segments and calculate the field contribution from each segment in ...
