Common uses of magnets

Magnetic field The magnetic flux density also called magnetic B field or just magnetic field, usually denoted B is a vector field.

Common uses of magnets

Common uses of magnets include the compass, vending machines, refrigerator magnets and electric motors. Some types of trains even levitate above magnetized rails!

Common uses of magnets

Without magnets, the world would be a very different place. Compass A compass uses a magnet to direct its needle to the north pole. This is why magnets are said to have a north and south pole. The side that is attracted and points to the north is called the north pole, while the other end is the south pole.

Children can easily learn about magnets in a compass by crafting one with a needle, cork and a bowl of water.

Industrial Uses of Polyester

Magnetize the needle by rubbing it with a strong magnet. Then, place the needle on top of a cork floating in water. It will point to the north. Mag-Lev Trains Magnetically levitated trains, known as mag-lev trains, use magnets under the cars to float above the magnetic tracks because the magnets are repelling each other.

These types of trains use superconducting magnets and can travel up to miles per hour.

Common uses of magnets

Mag-lev trains are used in countries such as Japan. The United States government is working on bringing the technology to America. Sciencing Video Vault Vending Machines Coins are separated and sorted inside vending machines with magnets.

These magnets sort out metal disks or slugs from the real coin money. Also, paper money and checks have magnetic dust in their ink. Vending machines and currency counters check the money for its magnetism to insure the money is genuine.

Holding Things One of the most common uses of magnets is to hold things together. Paper shopping lists and your book report can be held up on refrigerator doors with fridge magnets.

The magnets stick the paper to the door with its attraction to the metal in the door. Also, the actual refrigerator doors stay closed because of magnets in the door frames.

Electric Motors Magnets are responsible for making electric motors and generators work. Moving a metal wire near a magnet produces electricity. Electric generators use steam, flowing water or another source of energy to spin wires through a magnetic field and create electricity.

Every time you turn on a light or watch television, you can thanks magnets for helping produce electricity.3 Unusual Uses Of Magnets This entry was posted on July 27, by Apex Magnets. While we use magnets for countless different things every day, people are still coming up with new, innovative ways to harness the power of magnetism for their own purposes.

Every segment of society uses minerals and mineral resources everyday. The roads we ride or drive on and the buildings we live learn and work in all contain minerals. Below is a selected list of commonly used metallic and nonmetallic minerals, ore minerals, mineral byproducts, aggregates, and rock.

These are some of the strongest magnets you will ever use! Great for door catches - or embed a magnet into wood to make a refrigerator magnet.

Common uses of magnets include the compass, vending machines, refrigerator magnets and electric motors. Some types of trains even levitate above magnetized rails! Without magnets, the world would be a very different place.
