An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor. Electric motors are used in all sorts of applications. There are even several electric motors inside your computer including one to turn the fan, one to open and shut the CDROM drive, and one to operate the hard drive.

One of which is an electric motor. An electric motor can actually covert electricity into movement. They can generate magnetic fields by using an electric current, just like in a circuit. If you coil the wire around a piece of metal, you can produce a bigger magnetic field. The tighter the wire, the bigger the magnetic field. The field will then cause a magnet to spin.]]> 2021-12-02 15:10:19 UTC https://padlet.com/1530267/g8j8b5w1pebhcnpi/wish/1925380380 1530267 https://padlet.com/1530267/g8j8b5w1pebhcnpi/wish/1931210489 Electromagnet, device consisting of a solenoid (usually a cylindrical coil of insulated wire wound in the form of a helix), in which an iron core is placed. An electric current passed through the coil induces a strong magnetic field along the axis of the helix (see induction; magnetism). When the iron core is placed in this field, microscopic domains that can be considered small permanent magnets in the iron align themselves in the direction of the field, thus increasing greatly the strength of the magnetic field produced by the solenoid. The magnetization of the core reaches saturation once all the domains are completely aligned, and an increase of the current in the solenoid has little further effect. The iron loses its magnetism quickly when the electric current stops flowing through the wire.]]> 2021-12-06 14:20:58 UTC https://padlet.com/1530267/g8j8b5w1pebhcnpi/wish/1931210489 1530267 https://padlet.com/1530267/g8j8b5w1pebhcnpi/wish/1931338500 An electromagnet is a device that has a (usually iron) core that has a (usually copper) wire coiled around it. When an electric current passes through the (usually copper) coil, it starts to create a weak magnetic field along the (usually copper) coil. When the (usually iron) center is put into the field, the domains in the (usually iron) core align themselves in the direction the field is facing. This can make the magnetic field produced by the (usually copper) coil a lot stronger. The (usually iron) core quickly loses it's magnetic power when the (usually copper) coil stops producing an electric current.
