Most electric motors use electromagnets because they can be easily controlled by adjusting the electric current flowing through them, allowing for precise speed and torque control. Additionally, electromagnets provide stronger magnetic fields compared to permanent magnets, making them more efficient for many industrial applications.
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.
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.
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.
The electric motor is the most important device used to convert electricity into motion. It functions by generating a magnetic field that interacts with electrical currents to produce rotational motion. Electric motors are widely used in various applications, from household appliances to industrial machinery, due to their efficiency and versatility.
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).
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.

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.
Magnets are used in a variety of devices such as electric motors, generators, MRI machines, and speakers. They work by creating a magnetic field that interacts with other materials, allowing for the conversion of energy or the manipulation of objects without direct contact.
Many objects have magnets in them. Electric motors and speakers use them. Refrigerator magnets and similar objects use magnets. The magnetron of a microwave oven usually contains two large magnets. Even some types of fake earrings use magnets.
Most electric motors change electrical energy into rotational mechanical energy. A few electric motors change electrical energy into linear mechanical energy.
Most motors aren't wired with solid wire. Typically only alternators or electric motors have solid wire.
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.
