Moreover, the experiment also demonstrated how the different configurations of resistors, parallel or in a series could play a role in the behavior of the circuit and its components. References :  R.

Galvanometer has a word called sensitivity of galvanometer is defined as the current in micro ampere required to consume one millimeter deflection on a scale placed 1m away from a mirror. As with other formulas galvanometer has its own formula called a=the angle of deflection of the coil. Although, the currency of moving coil meters is dependent upon having a uniform and magnetic field. Is a very sensitive instrument used to measure the small currents of the order. Galvanometer gives the deflection which is proportional to the electric current flowing through it.
The experimental value yielded a result of y = -100x + 10 and the theoretical yielded a -100 V/m. The percent error between the two values was 0.00%. The experiment showed that the theory of the relationship between equipotential lines and electric field lines hold true. Introduction: The objective of this lab was to analyze the nature of electric fields formed by two dipoles and two parallel line conductors using a digital voltmeter. The purpose is to test the theory that states equipotential lines always run perpendicular to electric field lines.
These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Diamagnetism is the tendency of a material to oppose an applied magnetic field, and therefore, to be repelled by a magnetic field. Paramagnetism is a form of magnetism whereby certain materials are attracted
The magnetic field produced is given by B= (8µ_0 NI)/(√125 a) (2) where µ_0 is the permeability of free space 4π×〖10〗^(-7)WB/A-m, N is the number of turns 72 for this experiment, I is the current and a is the mean radius of each coil .33 meters. The magnetic field through the Helmholtz coil is shown in Figure 1. The region of this magnetic field that we are concerned with is in the center where the magnetic field lines are nearly uniform. When an electron is accelerated by a potential difference V, it gains kinetic energy equal to the work done on it by the field which is given by 1/2 mv^2=Ve (3) Where V is the anode potential and e is the charge of the electron. The force on an electron traveling perpendicular to a magnetic field is given by F=Bev
This was followed by the second wave that started towards the end of World War Two and lasted until the 1960s. The second wave also encountered a reverse wave that lasted from 195-1975 (Huntington, pg.16). The third wave began in 1974 and has continued to present times. In each of these waves different forms of government were created and destroyed with many different paths being taken. Samuel Huntington has examined these waves, particularly the third wave and has come up with three different paths that democratization can follow, transformation, replacement, and transplacement.
While it is true that psychologists such as Francis Galton (1908) were theorizing on the possibilities of more than one memory system, it was R. Atkinson and R. Shiffrin (1968) who created the first multi-store model. This model suggested that outside stimulus was encoded into short term memory through the sensory register, and can stay in short term memory for up to twenty seconds, after which it is either forgotten or transferred into long term memory. Information stays in short term memory through continuous rehearsal. H.M displayed this when he was given a 3 digit number and asked to remember it. Through continuous rehearsal, H.M could hold those three digits for up to 15 minutes.
Another definition for electromagnets are solenoids wound around a central iron core. The magnetic field generated by the coil of wire magnetizes the core, increasing the total field. The difference in simple terms: a solenoid is a long, thin helical loop of wire. An electromagnet is a magnet whose magnetic properties depend on an electric current. A solenoid is just a coil of wire, but when you run a current through it, you create an electromagnet.

Motion is the change in position over time against a reference point, and is the procedure of an object changing place or position. Sir Isaac Newton, a famous mathematician and scientist, had created three laws based on motion. The first law was based on inertia, the tendency of an object to resist any change in motion, which states, “Objects at rest, stay at rest, unless acted upon by a force,” and, “Objects in motion, stay in motion, unless acted upon by a force.” This law explains that if an object were to travel at a constant speed in the same direction, it would continue to do this until it is pulled or pushed by something. If we think about a gravity-free zone, such as space, we could picture throwing a rock out into outer space. And this marble would continue to go at the same speed in the same direction unless there is a force, a push or pull, acting upon by it, making it either slow down, speed up, or just change it’s direction.
