Solenoids are spring-shaped coils of wire commonly used in electromagnets. If you run an electric current througha solenoid, a magnetic field will be generated. The magnetic field can exert a force on charged particles that is proportional to its strength. To calculate the force from a solenoid...
In combination with the equation for the magnetic flux of a solenoid and the equation for the magnetic field of a solenoid. The corresponding equation can be seen below: {eq}Magnetic \ Flux \rightarrow \Phi = B A {/eq} {eq}Magnetic \ Field \rightarrow B=\frac{{\mu}NI}{l} {/eq...
Analytical methods to calculate electromagnetic stress of superconducting solenoid magnetsCompressive radial stressElectromagnetic stressSuperconducting magnetTurn-to-turn contactCompressive magnetic radial stress is favored, over tensile one, for a high field magnet, mainly because it lowers the overall peak ...
An armature is the rotating solenoid inside of DC machines. Engineers use DC machines to build a generator or a motor. When it's used as a generator, a gas turbine or a diesel engine rotates the armature and the armature generates electric power. When it's used as a motor, electric pow...

The net force from both wires on the charge is in the negative x direction, and the goal is to find the current in each wire using the equations for magnetic field and force. By finding the individual magnetic fields from each wire and taking the difference, the curre...
To determine the number of turns, n, needed in the coil to produce a certain magnetic field strength, B, along its axis, use the formula B=?ni, where ? is the magnetic permeability constant and i is the current running through the wire. ...
