    Energy comes in many forms. Electric energy can be converted into useful work‚ or mechanical energy‚ by machines called electric motors. Electric motors work due to electromagnetic interactions: the interaction ofcurrent (the flow of electrons) and a magnetic field. Problem Find out how to make a simple electric motor. Materials Needed D battery Insulated 22G wire 2 large-eyed‚ long‚ metal sewing needles (the eyes must be large enough to fit the wire through) Modeling clay Electrical tape Hobby

    CONCEPTS HARD AND SOFT MAGNETIC MATERIALS: Materials‚ which are difficult to magnetise and de-magnetise. Soft materials are easy to magnetise and de-magnetise. MAGNETIC FIELD: The area around a magnet where another magnet would feel a force. MAGNETIC FIELD LINES: Show the direction of the magnetic field. The lines run from North to South. Where the field is strong‚ they are close together. INDUCED MAGNETISM: A magnetic material can be magnetised by being placed in a magnetic field. ELECTROMAGNET:

    Product Fabrication SemiTech Mr. Mark Benjamin Engineer SemiTech Dear Mr. Mark Benjamin This is the report for analyzing and recommends dope silicon for our company. In the report‚ I use the right-hand rule to determine the direction of the magnetic field‚ force acting in charge and the direction of moving charges. After that I use several equations to calculate the carrier concentration‚ hall coefficient‚ of the sample. It is an n-type semi-conductor. The resistance of the sample is 1.756

    when we say a substance is magnetic. (HINT: Be sure to mention the role of the Electrons) If a substance is magnetic‚ we are actually saying that it is able to be acted upon by a magnetic field. When electricity flows through a circuit‚ it creates a magnetic field.When a magnet cuts across a circuit‚ a voltage is produced. 2. Discuss the relationship between electric and magnetic fields. (HINT: Be sure to discuss what happens when electric current is applied to a magnetic field.) The relationship

    Introduction The purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then

    of the electron‚ in this case. After emerging from the hole in the anode‚ the electrons enter a region with no electric fields‚ therefore then traveling at a constant velocity. The beam’s path is illuminated due to the ionization of the gas. A magnetic field is applied to the beam using Helmholtz coils. Helmholtz coils are two vertically orientated‚ identical circular coils of wire (solenoids) that are placed parallel to each other‚ symmetric along a shared axis‚ one on each side of the domain

    realization that an electric current created a magnetic field around the conductor. It was then discovered that this effect could be enhanced greatly by winding the conductor into a coil. The effect proved to be two-way: If a conductor‚ maybe in the form of a coil was placed in a changing magnetic field‚ a current could be made to flow in it; this is called induction. So imagine a coil‚ and imagine that we apply a voltage to it. As current starts to flow‚ a magnetic field is created. But this means that
