For example, a uniform electric field E is produced by placing a potential difference (or voltage) ΔV across two parallel metal plates, labeled A and B.
How is a uniform field formed?
A uniform field is created in the gap between the two poles.
How can you produce uniform electric and magnetic field?
An electron moves in such a way that its velocity remains in the direction of electric filed.
What device produces a uniform electric field?
Answer: c) Two parallel plates.
How is uniform magnetic field produced?
A uniform magnetic field can be made by making a relatively long cylindrical coil. Once current is flowing through the coil a uniform magnetic field will exist all along the inside of the coil. … Helmholtz coils can be bought for the very reason of supplying a uniform magnetic field.
What is the electric potential in a uniform electric field?
The difference in electric potential energy is measured with a voltmeter in units called volts. A constant electric field can be produced by placing two large flat conducting plates parallel to each other. The electrical potential difference in a uniform electric field is given as begin{align*}V = Edend{align*}.
Why is electric field uniform in parallel plates?
It is precisely because the field strength diminishes like 1/r^2 with distance from a point charge that when a charge is spread uniformly over parallel plates that have a large radius compared to their separation that the field strength over a fairly large part of the region between the plates is nearly uniform.
What is V KQ R?
v=kq/r means potential at r distance from and by q charge. potential due to point charge at r distance. now about v=w/q it is another definition of voltage :- force acting at distance by unit charge. w = work = force×distance.
What type of charge configuration would generate a uniform electric field?
The parallel or uniformly charged infinite plane configuration produces uniform electric field.
Which device produces uniform magnetic field?
A Helmholtz coil is a device for producing a region of nearly uniform magnetic field, named after the German physicist Hermann von Helmholtz. It consists of two electromagnets on the same axis.
When a charged particle enters a uniform magnetic field its kinetic?
when a charged particle enters a uniform magnetic field , its kinetic energy remains constant. The magnetic field always exerts a force perpendicular to the particle’s velocity, so the magnitude of the velocity remains constant and so does the kinetic energy.
What is uniform magnetic field?
A uniform magnetic field is represented by equally spaced parallel straight lines. The direction of the flux is the direction in which the north-seeking pole of a small magnet points. The lines of flux are continuous, forming closed loops.
