de-magnetise. MAGNETIC FIELD: The area around a magnet where another magnet would feel a force. MAGNETIC FIELD LINES: Show the direction of the magnetic field. The lines run from North to South. Where the field is strong‚ they are close together. INDUCED MAGNETISM: A magnetic material can be magnetised by being placed in a magnetic field. ELECTROMAGNET: A current-carrying coil of wire (SOLENOID) often wrapped around a soft magnetic core which produces a magnetic field quite like a bar magnet

Electromagnets! An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electrical devices‚ such as motors‚ generators‚ relays‚ loudspeakers‚ hard disks‚ MRI machines‚ scientific instruments‚ and magnetic separation equipment‚ as well as being employed as industrial lifting electromagnets for picking up and moving heavy iron objects

affect with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure‚ chemical reactions‚ the attractive and repulsive forces associated with electrical charge and magnetism‚ and all other electromagnetic phenomena. According to Coulomb’s Law‚ we know electric charges get Coulomb force in the electric field while current receives another applied force‚ which is Ampere force when it is in a magnetic field. Overall‚ electromagnetic force

Induce a magnetic field and fit around the armature. | The magnets supply the magnetic field which interacts with the current in the armature to produce the motor effect. | Armature | The armature consists of a cylinder of laminated iron mounted on an axle. Often there are longitudinal grooves into which the coils are wound. | The armature

Multicultural Field Trip (Statue entering the center) Here in my area of California there are many choices to choose from for my field trip to a cultural center. After searching online I decided on the WorldBeat Cultural Center located in San Diego California at 2100 Park Blvd San Diego 92101. I knew I had chosen a good site when before I even entered the center as I heard beating of drums in a mesmerizing rhythm while still parking my car. The name WorldBeat was fitting.

loop that is able to rotate in a magnetic field. The electric motor uses electrical energy to make the loops rotate which creates mechanical energy. In the electric generator it uses mechanical energy to make the loops spin resulting in the creation of electric current within the loop. The way an electric generator functions is based on the principal of "electromagnetic induction". Electro magnetic induction is when you move a wire through a magnetic field causing electric current to enter the wire
