Abstract

DC motors are employed and used in various applications to perform various tasks which require the conversion of electric current to mechanical motions. In most cases, DC motors are used as actuators to convert the electric current from the output of a control system to a mechanical motion for a present function. This experiment employed the use of simple and easily available materials to construct a simple homemade DC motor. The project used basic components such as coil of wire, permanent magnet and simple dc battery to construct a simple device which demonstrated the operation of a simple DC ...

Abstract— Faraday's Law is used to estimate the magnetic field of the magnet from the maximum induced voltage. This paper presents the report of the experiment on Faraday’s Law of induction. In this experiment Faraday's Law and Lenz's Law are examined, along with the concepts of magnetic flux and conservation of energy. The experiment was carried out by using a wand having a coil at its end. This coil is made to swing through the magnetic field of a horse magnet. The induced EMF stated by Faraday and the reason for the minus sign added to it by Lenz has been ...

Lab Section

- Theory
When charged particles flow through a given magnetic field, force is exerted on them. Likewise, charged particles that are in motion induce magnetic fields around the conductor in which they flow. Biot-Savart law is stated by the formula shown below;
dB=μo IdL*r4πr3
In the formula, µo represents the permeability of free space, r represents vector displacement pointing from the section of the wire carrying current to the point whose magnetic field is being determined, and dl refers to a vector quantity with the value equal to the length of the segment of current. ...

Theory

A magnetic field refers to magnetic control of electric currents and the magnetic materials, specified by both direction and strength. It results from moving electric charges and the magnetic moments of elementary particles related with their spin. It can also be defined as its force exerted on a charged particle in motion. Magnetic field lines normally form in concentric circles around a current currying conductor cylindrical in nature for example a length of wire. The strength of the magnetic field is inversely proportional to the length of the wire or the distance for an infinite length.

Biot–Savart law describes the magnetic field generated by a steady current, I to be equivalent to;

Introduction.

Current generates magnetic field β of which its direction and magnitude highly depends on the geometry of the coil in which charge flows through. Coils can have different geometric shapes; circular, torus and two circular coils with current flowing in either the same or opposite direction. In such different coil geometry therefore, the magnetic field β can be determined using Ampere’s and Biot-Savart Laws’.

Instruments/apparatus.

- Bar magnet.
- Insulated copper wire Circular and toroidal coil
- Cardboard tube.
- Galvanometer.

Procedure and Observation.

- The insulated copper wire was wrapped around the cardboard tube to form a single circular coil and ...

Abstract

The experiment is aimed at constructing a step-up transformer. This is due to the type of materials being used and the number of rolls that the wire is rolled on the U-shaped material. This can easily be related to the alternating current that is tapped from one source to the other. This current can easily be measured in respect to the size of the voltage that is alternated in between the primary transformer and that of the secondary transformer. The number of coils in the primary material is two; the other secondary coil has four coils. The material used to ...

Horse-run carts portrayed the streetscape right up until the commencement of the previous century, but the arrival of the vehicle, which Carl Benz and Gottlieb Daimler created separately of one another in the year 1886, instituted a totally fresh combination of needs as compared to those connected with horse-run carts – particularly where the suspension was a concern: it was essential to handle superior pace, without jeopardizing road travelers. Carl Benz and Gottlieb Daimler assumed dissimilar approaches to this issue: while Benz chose the cycle as the initiating point for his Copyright Motor Car and employed a navigating head plus ...

Introduction.

The magnetic field β, in a solenoid coil of N turns with a medium magnetic permeability μ and length ɭ through a current flow ɪ, can be computed from the following equation.
β = μNɪ ---------- equation 1.
β = μNɪ ɭ = μNɪ ---------- equation 2.
ɭ (ɭ2 + D2)½ (ɭ2 + D2)½
The above equation 1 only provides the magnetic field strength at the center of the coil, but because unavoidable parallax errors on measurement would normally arise, the equation is modified by a correction factor D, the coils diameter and appears as in equation 2. Depending on the direction of currents flow, magnetic field in a wire or a solenoid coil ...

Introduction

There are many resemblances that can be observed in magnetic and electric phenomena. A magnet comprised of north and south poles which are opposite to each other. The opposite poles attract and likewise repel each other. A magnet has principle property to influence the surrounding space. This surrounding effect of a magnet is known as a magnetic field.
Magnetic fields consist of lines of force and force of attraction and repulsion that travel/or move along the lines. The developed forces depend on strength and distance apart the poles.

Abstract

The word technology may be in the talk of time for most individuals, however, little do they know what impacts all this development. The existence of visual systems, audio systems and other complex equipment all give credit to the early discoveries. Discovery of atoms, ions and later electrons simplified everything. It is from theses that energy was developed. One of the most promising techniques used by scientists is the charge to mass ratio of electrons. It helped in observing the nature of materials. This lab report aims at analyzing the Sir J. Thompson`s experiment of evaluating charge to ...

Introduction:

In a typical hydroelectric power generation system, a dam (water reservoir) is built near water body such as a river to create head (height) that enables water to flow at high pressure via a pipe (penstock) to the turbines that drive the power generators. The fast moving water turns the turbine blades at high velocity, and in turn, the turbine turns the electricity generator’s rotor. The wire coils in the generator’s rotor sweep past the stationary coil (stator) in the generator thus producing electricity. This concept was first demonstrated in 1831 by Michael Faraday, who discovered that ...

Introduction
For the past couple of decades since the onset of the Industrial Revolution, scientists have slowly began a campaign to raise awareness to the changing state of the planet. Records of high temperature changes, onset of diseases and erratic weather patterns have been reported worldwide, each change becoming more severe as the years progress. When it comes to erratic weather patterns, scientists highlight the now common occurrences of natural disasters such as hurricanes or cyclones. Although skeptics stress that ...

Multi-driver speaker systems require ‘Crossovers’ as their subsystems and are primarily used for the separation of input signal on the basis of driver into various different frequency ranges. The power which is received by the drivers is only in their usable frequency range and therefore the distortion which is caused in the drivers can be reduced with the use of crossovers. Crossovers are only helpful in order to minimize the distortion and it is not possible to completely block at the passband edges, similarly amplitude variation and face changes also cannot be completely restricted.
Crossovers are primarily of ...
