This field can be visually represented by field lines emanating from the north pole to the south pole of a magnet. Understanding the nature of magnetic fields is fundamental to electromagnetism and has practical applications in everything from electric motors to the functioning of electronic devices....
美 英 na.磁场 网络的磁场 复数:magnetic fields 权威英汉双解 英汉 英英 网络释义 magnetic-field n. 1. 磁场an area around a magnet or magnetic object, where there is a force that will attract some metals towards it 例句
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...
magnetic field n.the lines of force surrounding a permanent magnet or a moving charged particle 同义词:magnetic fluxflux 学习怎么用 双语例句 用作名词(n.) It shows the presence of a magnetic field. 这表明有磁场存在。 Total field measurement is not always desirable. ...
A. placing the magnetic needles around the magnet B. determining the polarity of the magnet C. drawing the magnetic field lines D. changing the distance between the magnetic needles 相关知识点: 试题来源: 解析 B。解析:在关于磁场线的实验中,首先要确定磁铁的极性。选项A,在磁铁周围放置磁针是在确...
In simple terms, a magnetic field is a region of space where a magnetic force can be detected. This force acts on moving charged particles, such as electrons or protons, and on magnetic materials like iron. It's often visualized using lines of force, also known as magn...
A strong magnetic field can constrain electrons to move only along the field lines. 强磁场可约束电子使之只能沿着场力线运动. 辞典例句 The spherical rotor is suspended by ultrasonic and is very high speed under surrounding magnetic field. 利用超声悬浮使球形转子悬浮起来,然后通过磁场使球形转子高速旋转...
Understand what a magnetic field is. Learn the definition of magnetic field lines and understand how one can detect magnetic field lines using a...
Magnetic field topologies between the Sun and Earth are important for the connectivity to Earth of solar suprathermal particles, e.g., solar energetic particles and the electrons in type III solar radio bursts. An approach is developed for mapping large-scale magnetic field lines in the solar ...
