These lines, called MAGNETIC LINES OF FORCE, do not actually exist but are imaginary lines used to illustrate and describe the pattern of the magnetic field. 9 a.m. - 12 p.m. Come outside for some coffee and conversation with Massachusetts State Troopers and Officers of the Milford Police Department. The scalar function whose gradient is the electric field is called the electric potential V and it is defined as. The designation is based upon the number of threads per unit length. The direction of this force can be represented by the imaginary lines. Each sarcomere is composed of two main protein filaments—actin and myosin—which are the active structures responsible for muscular contraction. This produces a pressure of 2.5 kg f cm −2 at every point within the fluid, which acts with equal force per unit area on the walls of the system. The concept of flux describes how much of something goes through a given area. A Pascal is one Newton per Square meter. The ampere is used to measure electricity much as "gallons per minute" is used to measure water flow. You can see that for a given force, if the surface area is smaller, the pressure will be greater. The thrust on unit area is called pressure. That is, The pressure unit pascal is too small for pressures encountered in prac-tice. Answer: (d) Explanation: Think of flux like weight.

If the pressure is held constant then the force is directly proportional to the area. Coulombs 3. "Magnetic flux density, B, is the force, F, per unit length, l, per unit current, I, on a current carrying conductor at right angles to the magnetic field. These are called Gauss lines. 20.4 F = qvBsinθ, where θ is the angle between the velocity of the charge and the magnetic field. That is, the emf is the work done on the circulating charge per unit charge (coulomb) displaced past a point of the circuit. Line of force, in physics, path followed by an electric charge free to move in an electric field or a mass free to move in a gravitational field, or generally any appropriate test particle in a given force field. Magnetic flux = number of magnetic lines of force = µ0 × m Where µ0 is number of lines associated with unit pole. Found inside – Page 210Each magnet has two poles called north pole ( N ) and south pole ( S ) . ... or lines of force passing per unit area through any substance through a plane ... The magnetic axis of the earth moves about within a circle of some 10–15 degrees of arc from the rotational axis. The magnitude F of the force experienced by this charge is. Measurement: Flux is a total, and is not “per unit area” or “per unit volume”. E = F / q. Found inside – Page 141-Any portion of non - conducting space disturbed by electricity is called an electric field . ... Indeed the resultant force at any point is directly proportional to the rate of fall of potential per unit length along the line of ...

Apparently, in order to maximize confusion, the term intensity, I, refers to power per unit area, and therefore we write the proportionality: I p 2. As number of lines of force per unit area gives the strength of the field, the field becomes independent of distance. The scalar function whose gradient is the electric field is called the electric potential V and it is defined as. In this instance, θ represents the angle between the magnetic field and the wire (magnetic force is typically calculated as a cross product).
