What Makes a Magnet?Magnetic WandsLearning Resources
C. Magnetic force. D. Frictional force. 相关知识点: 试题来源: 解析 B。解析:文章中提到“When an object is placed in water, it experiences an upward force called buoyant force. If the buoyant force is greater than the weight of the object, the object will float.”,所以使物体漂浮的力是...
there are rare man-made material mixtures that are conducive to becoming electromagnetic by being exposed to a strong magnetic field and holding an electromagnetic charge for long

What makes an object magnetic according to the Pauli exclusion principle? What is the sure test for magnetism? What are the properties of a magnetic field? Why is there no magnetic force on a stationary charge? Does magnetism go through iron? Why are diamagnetic substances repelled by magnetic...
Coils are the simple magnetic sensors that can detect changes of the magnetic flux density. As shown in Figure 1, when a magnet is brought close to the coil, the magnetic flux density in the coil increases by ΔB. Then, an induced electromotive force/induced current that generates a magneti...
