Question
The movable part of the solenoid is the magnetic field electromagnetic coil the plunger the armature How does the magnetic field change around a conducting wire if the current increases? The field grows stronger. The field grows weaker. There is not magnetic field around a conducting wire. It is impossible to predict. The quantity of lines of force per unit of area is known as magnetic flux flux density ampere-turns permeability A coil of wire with current flowing through it is called a(an) capacitor north pole south pole electromagnet Electromagnetic induction is best defined as the process by which a voltage is produced in a conductor when there is motion between the magnetic poles motion between the conductor and the magnetic field motion around the magnetic fields energy around the magnetic fields energy produced by the rotating coilsExplanation / Answer
1.) Armature
Electromechanical solenoids consist of an electromagnetically inductive coil, wound around a movable steel oriron slug (termed the armature). The coil is shaped such that the armature can be moved in and out of the center, altering the coil's inductance and thereby becoming an electromagnet. The armature is used to provide a mechanical force to some mechanism (such as controlling a pneumatic valve)
2) A. fields grow stronger
as current is directly proportinal to magnetic field and direction of magnetic filed can be calculated by right hand thumb rule where thumb represent current and wraped finger represent magnetic field.
3.) magnetic flux
The total number of magnetic lines of force leaving or entering the pole of a magnet iscalled MAGNETIC FLUX. The number of flux lines per unit
4.) electrmagnet
5.)motion between the conductor and magnetic field
induce emf = - change in flux
