20.1 Magnetic Fields, Field Lines, and Force
Because the magnetic field lines must form closed loops, the field lines close the loop outside the solenoid. The magnetic field lines are much denser inside the solenoid than outside the solenoid. The resulting magnetic field looks very much like that of a bar magnet, as shown in Figure 20.15. The magnetic field strength deep inside a solenoid is

Field Force and Field Flux. Fields have two measures: a field force and a field flux.The field force is the amount of "push" that a field exerts over a certain distance. The field flux is the total quantity, or effect, of the field through space. Field force and flux are roughly analogous to voltage ("push") and current (flow) through a conductor, respectively, although …
How Does a Capacitor Affect Conductor Motion in a Magnetic Field?
A capacitor and magnetic field are two separate components that can interact with each other. When a capacitor is charged, it creates an electric field between its plates. This electric field can then interact with a magnetic field, causing the capacitor to experience a force and possibly move. 2. How do capacitors affect magnetic fields ...
