What is Field strength: Definition and 367 Discussions
In physics, field strength means the magnitude of a vector-valued field (e.g., in volts per meter, V/m, for an electric field E).
For example, an electromagnetic field results in both electric field strength and magnetic field strength.
As an application, in radio frequency telecommunications, the signal strength excites a receiving antenna and thereby induces a voltage at a specific frequency and polarization in order to provide an input signal to a radio receiver. Field strength meters are used for such applications as cellular, broadcasting, wi-fi and a wide variety of other radio-related applications.
Here is my solution. I completed this problem to the best of my ability and I am asking for someone to check and correct my solution if possible. I am not sure if my answers are correct, although and my thinking might also be flawed :confused:
q1= 6.0e-6C
q2= 1.5e-6C
q3=-2.0e-6C

Hey!
I've got my A-Level Physics exam on Thursday, and I'm just doing some past papers and I'm totally confused! Please help!
One of the questions (multiple choice) was saying which statement was incorrect.
The answer was: Electric potential is zero whenever electric field strength is...
Q: "The Earths radius is 6700km. Show that the magnitude of the gravitational field strength at a height of 350km above the Earth's surface is about 9 N/kg"
I got the mass of the Earth which is 5.98E 24
G the constant = 6.67E -11
Formula : g= GM/r² , i can't seem to get 9, am I supposed...
I have racked my brain for the past two hours and I can't figure this out. If anyone can help me with, please do.
Two long parallel wires 6.00 cm apart carry 19.5 A currents in the same direction. Determine the magnetic field strength at a point 12.0 cm from one wire and 13.4 cm from the...
What is the electric field strength in a region where the flux through a: 1.0cm \times 1.0cm flat surface is: 65N\frac{m^2}{C}, if the field is uniform and the surface is at right angles to the field?

Since the field points at a right angle to the surface we have a norm...
I need help with the following question.
A diopole is made up of two charges, Q1 and Q2, that are separated by a distance of 1 meter. Q1 has a charge of +3C and Q2 has a charge of -3C. What is the electric field strength of the field set up by these two charges at a point exactly halfway...
What is the electric field strength at a point in space where a proton experiences an acceleration of 1 million "g"?
I'm completely lost on this one I know it's bound to be something simple but I just can't figure out where to start with it, well other than that 1 million "g" should be...
I'm kinda stuck on this question:
1. Calculate the magnitude ofthe magnetic f ield at a point midway between two
long, parallel wires that are 1 .0 m apar t and have currents of1 0.0 A and 20.0 A,
respectively, ifthe currents are (a) in opposite directions and (b) in the same
direction...
I am stuck on my physics homework. I can manage the latter question, how ever when i work out the first one my working out has no rhyme nor reason (nor a right answer). Any help will be great.
A small metal sphere on an insulating rod is placed on a top pan balance, as shown in the diagram...
Given are two charges +1 X 10^-6 and one 3 X 10 ^ -6 distnace of 10 cm apart
I know there is a poitn in between these two and it is 4 cm from the 1.0 X 10^-6 charge
But i am asked to plot the elctric field strength as a function
if the elctric field is pointing right, then positive...
am to design an experiment showing how magnetic field strength of a magnet varies with its temperature. i know i can use a hall probe to measure the field strength - but how do i vary the temperature, and ensure that this is uniform throughout the magnet?

I was just wondering. How come the gravitational field strength of the sun is much larger than the gravitational field strength of the moon at when you calculate both values at Earth's position?
Here's the problem:
A particle with a charge of 4.4nC is in a uniform electric field E directed to the left. It is released from rest and moves to the left. After it has moved 6.00 cm, its kinetic energy is found to be 3E-6 Joules.
a) What work was done by the electric force?
.000003 J
b)...
