I wired a quick weak electromagnet. How come when I put a small permanent magnet close to it, both sides of the permanent magnet (north and south) are attracted to the same side of the electromagnet?
An electromagnet attracts permanent magnets through the creation of a magnetic field. When an electric current is passed through the coil of the electromagnet, it creates a magnetic field that is strong enough to attract the permanent magnet towards it.
An electromagnet is a temporary magnet that is created when an electric current is passed through a coil of wire. On the other hand, a permanent magnet is a magnet that retains its magnetism without the need for an external electric current.
Yes, an electromagnet can attract all types of permanent magnets as long as the magnetic field created by the electromagnet is strong enough to overcome the magnetic field of the permanent magnet.
The strength of an electromagnet can be increased by increasing the number of turns in the coil, increasing the current passing through the coil, or using a magnetic core such as iron or steel to concentrate the magnetic field.
Yes, there are many practical applications of electromagnet attracting permanent magnets. Some examples include generators, electric motors, MRI machines, and magnetic levitation trains. This phenomenon is also used in many everyday items such as speakers, doorbells, and credit card readers.
