The most basic of electric motors consists of a permanent magnet and an electromagnet. This is not a requirement for all types of electric motors and most modern electric motors do not have permanent magnets. The stator and rotor are the two active elements of a simple electric motor and both have magnetic fields in the various types and designs of simple motors.
Theoretically, an airplane does not need to have any magnets in it, but most airplanes do contain magnets. Every electrical motor contains magnets, and small electric motors are used in various parts of an airplane, such as for raising and lowering the landing gear.
A clothes dryer usually has only one part that has any notable electromagnetic characteristics. (The electronic control circuit is not magnetic beyond the fact that it has wires that carry currents.) The part that employs magnetic fields in its operation is the electric motor. Most electric motors do not have permanent magnets in them but have field and stator coils that induce the electromagnetic fields. Only small electric motors (usually battery operated) use magnets due to space constraints.
It makes sense that since some magnets are called "permanent magnets," other magnets should be called "temporary magnets." But since when did English make sense? We usually call them "electromagnets" instead. Electromagnets are used in most electric motors, and cranes that lift scrap metal. They're also used in relays and the write heads of tape recorders (including video tape recorders).
Since electromagnets are used in most large electric motors,the answer is almost all industry.
There are magnets found in most electric motors which are throughout your car eg electric window motors. They are also in your alternator. I assume that they are also used in the needles on your dashboard too.

Most electric motors require magnet to operate on the principal of attraction. A motor can operate without any permanents magnets by replacing the with another coil of wire.

One application of magnets is in electric motors. These are used everywhere. Most computer hard drives used magnets, which uses similar magnetic technology as cassette tapes. Giant magnets are used for medical imaging in Magnetic Resonance Imaging (MRI) machines. These are only a few.
The CN fleetas of 2007 consists of 1548 locomotives, most of which are products of either General Motors' Electro-Motive Division (EMD), or General Electric/GE Transportation Systems.

A washing machine motor is similar to any electric motor. It is an AC (alternating current) electric motor. There are also DC (direct current) electric motors. Most electric motors in the house like in a vacuum cleaner or washing machine are AC because that is what you have in your house. Most electric motors in your car like the starter and windshield whipper motor are DC because they run on the cars DC battery system. DC and AC electric motors are a little different but work in a similar way. If you take a piece of iron and wrap a coil of wire around it it will become an electro-magnet while the current is going through the wire coil. An electric motor has special switches called brushes that turn the two or more electro magnets on and off. When you turn on the motor one of the coils is on and attracts a magnetic attached to a rotor. The magnet turns till it reaches the coil and strikes a brush that turns off the first electro magnet and turns on the next one so that the magnet keeps turning because it is now attracted to the next magnet. It keeps spinning around and around being attracted to different coils as they keep turning on and off, this of course happens very fast. What I've given you is a very simple description of how an electric motor works. Some motors are more complex with many magnets and coils but still work in this same basic way.
Most electric motors change electrical energy into rotational mechanical energy. A few electric motors change electrical energy into linear mechanical energy.
The most common use of magnets and magnetism in in electric motors and generators.The basic principle of a motor is that if a wire carrying a current is in a magnet field there will be a force on that wire. That wire will move if it can.The basic principle of a generator is that if a wire is moving in a magnetic field then a current is induced in that wire.
Most motors aren't wired with solid wire. Typically only alternators or electric motors have solid wire.
