Instantaneous dipolesare temporary dipoles. Inside an atom, electrons revolve around the nucleus in fixed paths, but their motion is random. Sometimes, these electrons become more concentrated in one particular region than in another. This gives rise to an instantaneous or temporary dipole. The mecha...
A superconductor is a material that permits electric current to pass through it without experiencing any energy loss. Standard conductors, like copper wires, possess a level of electricalresistance— this is what causes them to heat up when an electric current passes through them. Advertisements In ...
What is the process of magnetism? What is magnetic field strength? What would happen if the Earth had no magnetic field? Why is the magnetic force perpendicular? Why does the magnetic force push objects apart? How can a metal become a temporary magnet? What are two ways that magnetism is ...
according to HyperPhysics. When an external magnetic field is applied to a material, these current loops tend to align in such a way as to oppose the applied field. This causes all materials to be repelled by a permanent magnet; however, the resulting force is usually too weak to be ...
6.How can a transition metal form an ion with a charge of 3+ or higher?7.Identify three ways transition metals are separated from their ores.8.Explain how a metal can become a temporary magnet.9.Explain why some metals can act as permanent magnets.For each item in Column A,write the ...
Temporary Magnets Under certain conditions, a temporary magnet is a metal with a magnetic field. Electromagnets Using an electric current, a wire is coiled around ferromagnetic materials to create magnets. Magnetic fields are only produced by this type of magnet when electrical current is flowing. ...
Permanent magnets(also known as hard magnets) are those that constantly producing a magnetic field. This magnetic field is caused by ferromagnetism and is the strongest form of magnetism. Temporary magnets(also known as soft magnets) are magnetic only while in the presence of a magnetic field. ...
Each piece of the magnet will have its own pair of poles. This principle is referred to as “monopole magnetism,” meaning isolated north or south poles do not exist naturally. Even when broken or cut into smaller pieces, all magnets have two poles by default. Do Temporary Magnets Have ...
