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...
A magnet, or a magnetic material, is an object that has 2 poles, north and south, that attracts other magnetic objects and sticks them together. They do this through attraction. The poles are attracted to one another, so south gravitates toward north, and north toward south. But if you ...
There are several things to consider when choosing magnetic catches, one of which is the material. All magnetic catches feature a magnet, which is typically enclosed in a material. Some of them use plastic for this purpose. Plastic magnetic catches are inexpensive, versatile and long-lasting. Yo...
Although ferrite magnets are not as strong as neodymium, you can use them for different functional things. You don’t need to add additional coatings or other treatments for them to work well. So, you can use them for different industrial, commercial, or personal purposes like: Loudspeakers Ho...
A magnetic catch usually refers to a piece of hardware on a cabinetry door. The piece actually comes in two parts, one fitting on the door, and a second piece inside the door. The pieces are magnetized, so that when they come together, they firmly close the door without very much ...
of atoms, most things don't behave magnetically because the poles of the atoms are not aligned–the poles point in all different directions. When something aligns the atomic poles in a substance, the substance becomes magnetic. Electricity is one of the things that can align the poles of ...
Magnets don't delete things from hard drives because hard drives themselves are generally made with powerful magnets inside of them. If you leave a strong electromagnet close to a hard drive, it could cause damage to the hard drive, but this rarely happens. ...

1. Energy comes in many forms such as light, heat, sound, magnetic, chemical, and electrical. c. Describe the energy transformation that takes place in electrical circuits where light, heat, sound, and magnetic effects are produced (DOK 1-2) ...
"If things go as expected," Deng said, "We may see this train in commercial operation within the next three to five years." This prototype train has a body made entirely from carbon fiber and weighs a mere 13 tonnes. When it levitates, there is virtually no re...
