Magnets can be used to make jewelry. Necklaces and bracelets can have a magnetic clasp, or may be constructed entirely from a linked series of magnets and ferrous beads. Magnets can pick up magnetic items (iron nails, staples, tacks, paper clips) that are either too small, too hard to reach, or too thin for fingers to hold.
Giant paper clip erected in 1989 in Sandvika, Norway, to honor Vaaler's invention. This 23-foot-tall (7 m) clip is the Gem, not the one patented by Vaaler. Johan Vaaler (March 15, 1866 – March 14, 1910) was a Norwegian inventor and patent clerk. [1] He has often erroneously been identified as the inventor of the common paper clip.
Creating a makeshift magnetic compass. Pass Adam and Jamie built a makeshift electromagnet by wrapping wire around a metal screw and connecting it to some batteries. They then used the electromagnet to magnetize a paperclip, put the paperclip in a cork, and floated the cork in a cup of water to create a compass.
An electromagnet attracts paper clips when current is applied, creating a magnetic field. The electromagnet loses them when current and magnetic field are removed. An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. [17] The magnetic field disappears when the current is turned off.
Paramagnetic materials have a weak induced magnetization in a magnetic field, which disappears when the magnetic field is removed. Ferromagnetic and ferrimagnetic materials have strong magnetization in a magnetic field, and can be magnetized to have magnetization in the absence of an external field, becoming a permanent magnet. Magnetization is ...
In Klein’s case, a Postal Service spokeswoman said, the problem is the road. Hillman Ridge is paved but narrows to a width slightly larger than a pickup truck as it approaches Klein’s property.
Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. [2]
