If the magnetic field and the velocity are parallel (or antiparallel), then sinθ equals zero and there is no force. In this case a charged particle can continue with straight-line motion even in a strong magnetic field. If is between 0 and 90 degrees, then the component of v parallel to B remains unchanged.

Recall that the direction of an electric field is defined as the direction that a positive test charge would move. So in this case, the electric field would point from the positive plate to the negative plate. Since the field lines are parallel to each other, this type of electric field is uniform and has a magnitude which can be calculated with the equation E = V/d where V …
In summary, the direction of the electric field between the plates of the parallel plate capacitor shown in the drawing would be up if the magnetic field is decreasing in time. This is because the induced current in the wire would be counterclockwise, creating a positive charge on the bottom plate and a negative charge …

The magnetic field as a function of position between two capacitor plates during discharge is derived with the use of the integral form of Ampere''s law and real currents only.
The electric field between the plates of a parallel-plate capacitor is determined by the external emf. If the distance between the plates is d (see Figure 35.4) then the electric field between the plates is equal to (35.29) This time-dependent electric field will induce a magnetic field with a strength that can be obtained via Ampere''s law.

The direction of the magnetic field in a capacitor is perpendicular to the electric field and depends on the direction of the current flowing through the plates.

It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum, and, in that case, a capacitor is then known as a "vacuum capacitor."

We connect a battery across the plates, so the plates will attract each other. The upper plate will move down, but only so far, because the electrical attraction between the plates is countered by the tension in the spring. Calculate the equilibrium separation (x) between the plates as a function of the applied voltage (V). (Horrid word!
