A magnetic crane is a crane system that uses magnets to lift and move loads. The magnet is mounted on the crane hoist and can be opened and closed to extract or release the load as required. These cranes typically operate on …
In a motor, the stator is the part that remains motionless and the rotor is the part that moves. The basic principle for all working motors is the magnetic attraction and repulsion. Since …
Maglev trains use magnets on the train and guideway to levitate the train off the track. The north pole of the magnets on the train must face the south pole of the magnets on the guideway so they repel. south pole of the magnets on the guideway so they attract. north pole of the magnets on the guideway so they repel. north pole of the magnets on the …
The magnetic field of a refrigerator magnet is more than 10 times stronger than the Earth''s magnetic field. There are two units of measure for magnetic fields: gauss and tesla. One tesla equals 10,000 gauss. The Earth''s magnetic pull is about .5 gauss. A 1 tesla magnet is strong enough to pick up a car.
The lone particle is attracted to the wire, because the particles attracting it are more dense than the ones repelling it. Furthermore, the attraction felt by the lone charge must be purely electrical, since the lone charge is at rest in this frame of reference, and magnetic effects occur only between moving charges and other moving charges.

Magnets and Magnetization. People have been aware of magnets and magnetism for thousands of years. The earliest records date back to ancient times, particularly in the region of Asia Minor called Magnesia—the name of this region is the source of words like magnet.Magnetic rocks found in Magnesia, which is now part of western Turkey, …
Ferromagnets. Only certain materials, such as iron, cobalt, nickel, and gadolinium, exhibit strong magnetic effects. Such materials are called ferromagnetic, after the Latin word for iron, ferrum.A group of materials made from the alloys of the rare earth elements are also used as strong and permanent magnets; a popular one is neodymium.

Why Do Moving Charges Create a Magnetic Field? The Physics …
According to special relativity, an electric field in one reference frame might appear as a magnetic field in another reference frame (although there is also quite a bit of subtlety under this statement).. Now, to understand this and in particular, how exactly this relates to why magnetic fields are only produced by moving charges, we need to discuss the notions of …
Electromagnets create a magnetic field through the application of electricity. When you introduce the current, either from a battery or another source of electricity, it flows through the wire. This …
Magnetic Suction: Magnetism & Electricity Science Activity ...
Any moving electric charge creates a magnetic field around it. A loop of wire with a current creates a magnetic field through the loop. You can increase the strength of this field by piling up a lot of loops. The more loops, the stronger the magnet. Like a bar magnet, this coil of wire now has a north pole and a south pole, and is an electromagnet.
Magnetism is a subject that includes the properties of magnets, the effect of the magnetic force on moving charges and currents, and the creation of magnetic fields …
The Impact Of Magnets On Batteries: Exploring The Relationship
High magnetic fields can lead to a phenomenon called the "magnetic memory effect," where the battery gradually loses its ability to hold a charge. This effect is not commonly observed in modern lithium-ion batteries, which are widely used in …
The Impact Of Magnets On Batteries: Exploring The Relationship

Magnets are objects, which can attract, or pull, on some metals, like iron and steel. If you rub a piece of steel with a strong magnet, the piece of steel will become a magnet too. It has become magnetized. Other metals, like copper or gold, are not attracted to magnets. Magnets can also attract each…
Objects tend to approach minimum energy configurations. Another magnet example, if you put two bar magnets side by side, the north pole of one magnet will align with the south pole of the other. This will make the fields of one magnet oppositely directed to the other, mostly cancelling out the fields, and thus producing an energy minimum ...
These magnets are called electromagnets. About 200 years ago, scientists discovered that electricity and magnetism are close cousins. An electrical current produces a magnetic field, and a moving magnet makes an electric current. When electricity passes through a copper wire it creates a magnetic field around the wire.
A magnet is an object that attracts ferrous objects and has a magnetic field. A ferrous object is one that contains some amount of iron. Ferrous metals include steel and alloys of iron with other metals, including stainless steel. A magnetic field is the space surrounding a magnet where magnetic forces are exerted on ferrous objects.

In terms of the theory developed in this section, a current (I_1=+1.2) A flows from the positive terminal of the battery to the load on one conductor, and a current (I_2=-1.2) A returns to the battery on the other conductor. The change in sign indicates that the currents at any given distance from the battery are flowing in opposite directions.
