1. An object that is surrounded by a magnetic field and that has the property, either natural or induced, of attracting iron or steel. 2. An electromagnet. 3. A person, a place, an object, or a situation that exerts attraction: a village that is a magnet for tourists. [Middle English...
An electromagnet is a magnet that is created by running an electric current through a coil of wire. The magnetic field it creates is similar to that of a bar magnet. These electromagnets are used in particle accelerators to discover more about the universe, but they can also be used in ...
The closing of the switch 174 closes a circuit from 160 through the coil 184 of an electromagnet 186, through a lead 188 and switch 174 to the line 166. This circuit remains closed until the breaking of the contact at 132 opens the three switches 170, 172 and 174. The electro-magnet...
and a changing magnetic field can create an electric field. So a wave-shaped electric field (for example, the field created when a charged particle such as an electron moves up and down) can create a wave-shaped magnetic field, which in turn reproduces the wave-shaped electric field. These...
In the NMR apparatus the resonant conditions may be kept constant by adjusting the strength of the static magnetic field. The echo signal that is induced under the specific conditions is processed so
State two ways by which the strength of an electromagnet can be increased. Name an example of a non-contact force. What is super insulation? Name one device that uses an electromagnet. Why do resistors have tolerance? What is electrical susceptibility?
You can increase the strength of an electromagnet's field by Does a current-carrying wire produce a magnetic field? Does frictional force increase with applied force? If magnetic fields are what we get when charges begin to move, why do we need an electromagnet to perform the function of ma...
