There are different types of magnets that vary in their size and shape. You could find tiny magnets that are used by the electronic industry and giant magnets that are used for cyclotron experiments. Even the strength of the magnets vary widely. Simple magnets that stick to your refrigerator have about one tenth of tesla strength.

Apr 24, 2017 · How to Make Electromagnets Repel You can make electromagnets that repel with some small batteries, wire and iron nails. Wrap the wire around the nail and cut it with the wire cutters. Leave several inches of wire sticking out of either end. Types of Metals That Attract Magnets.
Stud Finders — These magnets are powerful enough to find hidden nails and other metal pieces inside walls. Magnetic Therapy — For those who use magnetic therapy as a healing tool, neodymium magnets fit the bill perfectly. There are different sized blocks to choose from depending on the size of the body being worked on.
These magnets are very convenient because the magnetic field can be controlled. The only down side is that electric energy is needed to create the magnetic field. Electromagnets . An electromagnet is a type of magnet that is composed of a battery and iron wire that uses electric current in order to generate a magnetic field.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. The magnetic field disappears when the current is turned off.
There are many different types of magnets. The core isn''t air, it is something that aids in producing magnetic effects, so electromagnets are typically stronger than a comparable aircore magnet. Aircore and electromagnets can be turned on and off. They both depend on currents of electricity to give them magnetic characteristics.
Round electromagnets. Round electromagnets generate a magnetic field when supplied with power, these electromagnets sometimes called "holding electromagnets" are used, for example, for holding or carrying magnetic metals. Generally speaking, this type of electromagnets is used when the magnetic field is required to work (magnetic field on

Electromagnet, device consisting of a core of magnetic material surrounded by a coil through which an electric current is passed to magnetize the core. An electromagnet is used wherever controllable magnets are required, as in contrivances in which the magnetic flux is to be varied, reversed, or switched on and off.
What types of magnets are there? There are three main types of magnets: Permanent magnets Temporary magnets Electromagnets. Permanent Magnets. Permanent magnets are those we are most familiar with, such as the magnets hanging onto our refrigerator doors. They are permanent in the sense that once they are magnetized, they retain a level of
