B. Magnets have a magnetic field. C. Iron is attracted by magnets. D. Magnets are useful in many E. xperiments. 相关知识点: 试题来源: 解析 A。假设是磁铁吸引铁,选项 A“Magnets can attract all metals”(磁铁能吸引所有金属)是错误结论,因为只有铁等一些特定金属被磁铁吸引。选项 B“Magnets ...
Metals can be magnetic and non-magnetic. The magnetic ones will produce a field around them, usually described as “ferromagnetic.” These metals are not magnetic by themselves in their natural state. Still, they can be attracted to objects that produce magnetic fields. Once magnetized, these me...
Antiferromagnetism:The alignment of adjacent ions at low temperatures make the material non-respond to the magnetic field. Yet, some atoms break free above a specific temperature, and the material becomes weakly magnetic. Magnetic Metals There are many different types of magnetic metal. They include:...
Magnets are materials that produce magnetic fields, which attract specific metals. Every magnet has a north and a south pole. Opposite poles attract, while like poles repel. While most magnets are made from metals and metal alloys, scientists have devised ways to create magnets from composite mat...

What contributes to the corrosion resistance of stainless steel? Chromium is added to steel to create stainless steel, which is corrosion-resistant. 2 Can steel be melted and recycled? Yes, steel can be melted and is often recycled in various industries. 1 Which metals are magnetic? Some metal...
Diamagnetic Metals and Magnetism Diamagnetic metals are actually repelled by magnets rather than attracted to them, and usually weakly. Materials are classed as diamagnetic when their magnetic moments act in opposition to the field applied rather than to enhance it. These materials include silver, lea...
