Iron - Iron is a naturally occurring metal that is highly magnetic. Iron is a key component in steel and is widely used in various industries and applications due to its strong magnetic properties.
Steel - Steel is an alloy of iron and other elements, such as carbon. Steel is magnetic due to the presence of iron in it.
Nickel - Nickel is a naturally occurring metal that is highly magnetic. It is often used in conjunction with iron and other magnetic materials to produce alloys with enhanced magnetic properties.
Cobalt - Cobalt is a naturally occurring metal that is highly magnetic. It is often used in conjunction with iron and other magnetic materials to produce alloys with enhanced magnetic properties.
Alnico (an alloy of aluminum, nickel, and cobalt) - Alnico is a magnetic alloy that consists of aluminum, nickel, and cobalt. Alnico has strong magnetic properties and is commonly used in applications that require a permanent magnet, such as electric motors and generators.
Neodymium (a rare-earth metal) - Neodymium is a rare-earth metal that is highly magnetic. It is often used in conjunction with other magnetic materials to produce strong permanent magnets.
Samarium-cobalt (a rare-earth metal) - Samarium-cobalt is a magnetic rare-earth metal that is commonly used to produce strong permanent magnets.
Ferrite (an iron oxide ceramic) - Ferrite is a magnetic ceramic material that is often used in applications that require a high-frequency magnetic material, such as magnetic cores for transformers and inductors.
Magnets - Magnets are objects that produce a magnetic field and have the ability to attract or repel other magnetic objects.
Refrigerator magnets - Refrigerator magnets are small magnets that are commonly used to hold paper or other objects to the surface of a refrigerator.
Speaker magnets - Speaker magnets are used in speakers to produce the magnetic field that drives the speaker cone.
DC motors - DC motors are electrical machines that convert electrical energy into mechanical energy. The magnetic field produced by the motor's armature and stator is what drives the motor's rotation.
Electric generators - Electric generators are devices that convert mechanical energy into electrical energy. The magnetic field produced by the generator's rotor and stator is what drives the generator's output.
MRI machines - MRI (magnetic resonance imaging) machines use magnetic fields and radio waves to produce detailed images of internal organs and tissues.
Maglev trains - Maglev (magnetic levitation) trains use strong magnetic fields to levitate above the tracks and move smoothly and efficiently.
Credit cards with magnetic stripes - Credit cards with magnetic stripes contain a small strip of magnetic material that stores information about the cardholder and the card's account information.
Cassette tapes - Cassette tapes are magnetic storage devices that were commonly used to store music and other audio recordings.
Hard disk drives - Hard disk drives are magnetic storage devices that are used to store digital data in computers.
Compact discs - Compact discs (CDs) are optical storage devices that use a laser to read and write data. Some CDs also have a small magnetic layer that is used to store additional information.
Computer floppy disks - Floppy disks were magnetic storage devices that were commonly used to store digital data in computers.
Video tapes: Video tapes use magnetic tape to store audio and video information. The magnetic tape is coated with a material that can be magnetized, and the audio and video signals are recorded onto the tape by magnetizing it in specific patterns.
Locks: Magnetic locks use electromagnets to lock and unlock doors. When an electric current is applied to the electromagnet, it creates a magnetic field that holds the lock in place. When the current is turned off, the magnetic field disappears, and the lock is released.
Jewellery clasps: Magnetic jewellery clasps use tiny magnets to hold jewelry together. The two ends of the jewelry are held together by the magnetic attraction between the magnets.
Fasteners: Magnetic fasteners are used to hold things together without the need for screws, nails, or adhesives. They work by using the magnetic attraction between two magnets.
Knife holders: Magnetic knife holders use magnets to hold kitchen knives in place. The knives are held securely against the magnetic surface, keeping them within easy reach.
Tool holders: Magnetic tool holders are similar to magnetic knife holders, but are designed for holding tools instead of knives. They are commonly used in workshops and garages to keep tools organized and within easy reach.
Chalkboards with magnetic surfaces: Chalkboards with magnetic surfaces are chalkboards that have a magnetic layer underneath the writing surface, allowing you to use magnets to attach notes, papers, or other items to the board.
Calendars: Some calendars use magnets to attach to a metallic surface, such as a refrigerator or a metal bulletin board.
Memo holders: Memo holders use magnets to hold notes or memos in place. They are commonly used on metal surfaces, such as refrigerators or filing cabinets.
Electromagnets: Electromagnets are magnets that produce a magnetic field when an electric current is passed through them. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
Solenoids: Solenoids are cylindrical electromagnets used for a variety of applications, including locks, relays, and switches.
Relays: Relays are electrical switches that use electromagnets to control the flow of electricity. When an electric current is applied to the coil, it creates a magnetic field that attracts the switch and completes the circuit.
Transformers: Transformers are devices used to change the voltage of an alternating current (AC) electrical supply. They work by using electromagnetic induction, with the magnetic field of the coil inducing a voltage in another coil.
Inductors: Inductors are electrical components used to store energy in a magnetic field. They work by using electromagnetic induction, with the magnetic field of the coil inducing a voltage in another coil.
Switches: Switches are electrical components used to turn electrical devices on and off. Some switches, such as relay switches, use electromagnets to control the flow of electricity.
Compass needles: Compass needles use the Earth's magnetic field to determine magnetic north. The needle is magnetized and suspended so it can rotate freely, and it aligns itself with the Earth's magnetic field.
Bar magnets: Bar magnets are simple rectangular magnets with a north and south pole. They are commonly used for educational purposes or for demonstrating the properties of magnets.
