Electromagnetic Devices Electromagnets are used in a number of everyday devices. One useful characteristic of an electromagnet is the fact that you can vary its magnetic force by changing the amount and direction of the current going through the coils or windings around it.ummary. Electromagnets are used in a number of devices, such as loudspeakers and tape recorders. Some electromagnets can be very strong and its power can be readily turned off and on, such as in junk yard electromagnets and electromagnetic locks.

Magnet An electromagnet is made from a coil of wire that acts as a magnet when an electric current passes through it but stops being a magnet when the current stops. Often, the coil is wrapped around a core of soft ferromagnetic material such as steel, which greatly enhances the magnetic field produced by the coil. The overall strength of a magnet is measured by its magnetic moment or, alternatively, the total magnetic flux it produces. The local strength of magnetism in a material is measured by its magnetization.

Questions and Answers It is fairly easy to build an electromagnet. All you need to do is wrap some insulated copper wire around an iron core. If you attach a battery to the wire, an electric current will begin to flow and the iron core will become magnetized.ust make certain that the material you choose can be magnetized. You can test your core with a permanent magnet. If a permanent magnet is not attracted to your core, it will not make a good electromagnet. An aluminum bar, for example, is not a good choice for your magnet's core.

- TENS, IFC, and GS all apply electrical stimulation to nerves and muscles via adhesive pads placed on the skin. These devices are powered by batteries, and some units have an adapter that allows powering from an outlet. Electricity has been used to treat pain for over 100 years. Early proponents of electricity were labeled as charlatans, but recent scientific studies have proven that electricity can reduce both acute and chronic pain. The exact mechanism of electrical stimulation’s beneficial effect remains controversial.

Electromagnets - What factors affect strength of an electromagnet? A coil of wire acts like a bar magnet when an electric current flows through it, it becomes an electromagnet. All the magnetic fields we can create are the result of moving charges. Electromagnets make fields through large currents in wires we make.

How does a magneto work? In an electromagnet there is a coil of wire around an iron bar (the armature). When you apply current to the electromagnet's coil (e.g. with a battery), the coil creates a magnetic field in the armature. In a generator, you reverse the process. You move a magnet past the armature to create electric current in the coil. A magneto consists of five parts:

Electromagnetism So in order to produce a much stronger and more controllable magnetic field we need to use electricity. By using coils of wire wrapped or wound around a soft magnetic material such as an iron core we can produce very strong electromagnets for use in many different types of electrical applications.

Electromagnet An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law (see drawing below). To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side.he magnetic field created by an electromagnet is proportional to both the number of turns in the winding, N, and the current in the wire, I, hence this product, NI, in ampere-turns, is given the name magnetomotive force.

Electromagnet An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of insulated wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the m

- An electromagnet is a device that sends electricity through a coil of wire to produce a magnetic field. This leads to a magnet that can be controlled -- turned on and off with the flip of a switch, or increased or decreased in strength. The coils are often wrapped around a regular magnet to make it stronger.

Questions and Answers Magnets are used extensively in high energy and nuclear physics. We use some of the most powerful magnets in the world and certainly some of the coldest. Ok, to answer your question. Yes, I know what an electromagnet is. I have to assume you want to know a little more than that. An electromagnet is a magnet that is created when electricity flows through a conductor. The magnetic field goes around the conductor. The typical way electromagnets are built is to wrap many coils of wire around a ferromagnetic core (almost always iron).
