    A magnet is a material or object that produces a magnetic field. It is a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth

    understand the basic foundation of electromagnetism. The field of electromagnetism was only six years old when Henry began teaching at the Albany Academy in New York. Danish scientist Hans Christian Oersted had discovered in 1820 that an electrical current in a wire from a battery caused a nearby compass needle to deflect. The theory has been expanding from that

    4.11 Motor A DC motor is an electrical machine which converts electrical energy into mechanical energy. A magnetic field is generated by the current carrying conductor and when this system is placed in external magnetic field then the force is exerted which is proportional to the strength of the external magnetic field and to the current in the conductor, then motor will rotate. If the direction of current is reversed then the direction of rotation of motor will also reverse. The speed of DC motor

    strength of the magnetic field (the electromagnet’s strength) will also increase. This means that the number of paper clips that attach to the electromagnet will increase. Explanation of Hypothesis/background: When a DC (Direct Current) electric current flows through a wire, a magnetic field is created. Wrapping the wire in a coil concentrates and increases the magnetic field, because the additive effect of each turn of the wire. (When a coil of wire is used to create a magnetic field, it is

    Cell phones, microwaves, and even refrigerators are part of an average human’s daily life. These three items all use magnets. Magnets are used all the time in one’s normal day. The Earth itself is a magnet! (Blatt and Kendall). Magnets function through the North and South Pole. Each side has a positive and negative that either pushes or pulls depending on the charge it is reacting with. A North Pole (negative) repels another negative, but attracts a South Pole (positive). This is the same for a

    Introduction to Physics Lab (ZBT1) Electromagnetic Induction Marc Westover C164 ZBT1 Task 2 Professor Taha Mzoughi 03/14/2017 Introduction This experiment describes a physics lab on electromagnetic induction. It will test if coils of looped wire produce an electric current and if the number of coils makes a difference in a reading. The testing of electromagnetic induction goes back to 1831 with experiments conducted by Michael Faraday. His experiment led to one of the “basic laws of electromagnetism

    mathematical expressions. Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. The circuit equations can be determined using Ohm’s Law, which gives the relationship between voltage and current in a resistor (V=IR), and Kirchhoff’s Current and Voltage Laws, which govern the currents entering and exiting

    Introduction The purpose of this project is to design and build a functional roller coaster for a marble or, if possible, multiple marbles. The base of the roller coaster must be lesser than 1m x 1m.This roller coaster is run based on conservation of mechanical energy. The scientific concept of force, motion and energy, which we had learnt this year, have been applied into this project. My roller coaster model consist of seven loops, two layer of spiral (horizontal loops) and a funnel at the end

    Materials and Methods A frog leg was used for the muscle in the experiments. The skin was removed to expose the gastrocnemius, and the bone was severed just below the achilles tendon. The femur was cut just above the knee, and the tibiofibula was severed just below the knee. Ringer 's solution was applied to the muscle to keep the muscle moist. The procedures were done using a power lab, and a force transducer with a micropositioner. The force transducer was calibrated to give data in Newtons.

    Does the type of battery used to create a motor affect the time the motor spins? If the type of battery affects the amount of time the coil spins then the D-battery powered electric motor will spin for the longest period of time. The procedures were to create the motor and find a spot for the motor to spin. You also needed to keep track of the time the motor spinned. When the motor stops spinning record the time on a data table. The independent variable was the type of battery used for the motor

    Centripetal Force and Centrifugal Force The component of force that acts on a body in curvilinear motion which coordinates towards the focal point of curvature or axis of rotation can be defined as Centripetal force. Whereas, centrifugal force is defined as the apparent force, equivalent and inverse to the centripetal force, draws a turning body away from the focal point of rotation, which is caused by the inertia of the body. CONCEPTS These forces have different concepts where one of the forces

    The mural on the radio city had a central section that showed a large hand holding a sphere emerging from an ambiguous machine (Linsey 50). These features explore the major theme of the art that of the interrelationship between the biological and the physical world (Linsey 50). The mural also depicts a clear bolt of lightning being captured by electrical equipment. These images have a common source in mass culture history, that of real scientific experiments (Linsey 50).

    The purpose of this experiment was to use charged electrodes on conducting paper and voltmeter to discover electric field. The experiment also discovered the relationship between equipotential lines and electric field lines. The purpose of the experiment was to find if the theory that equipotential lines always run perpendicular to electric field lines hold true. The equation used in this experiment is E = ∆V/∆d. The experimental value yielded a result of y = -100x + 10 and the theoretical yielded
