(Some terms may be used more than once.) 1. All magnets consist of a pair of poles, called a dipole which consist of a more than and a south pole. Even the smallest magnet will have a pair of these poles. As far as we know today, there is no mono pole which is a single magnetic pole. 2. A strong, magnet consist of magnetic domains which are aligned and point in the same direction. Serromagnetic materials such as iron, nickel and cobalt can easily become magnetized in a magnetic field. However, these permanent magnets can become demagnetized if exposed to and 3. An is a temporary magnet which is formed by electric current flowing through coils of wire, or a solenoid. The more loops of wire in the solenoid, the the magnetic field will be. 4. The magnetic field of a magnet can be represented by magnetic which are imaginary lines that map out the magnetic field. The field lines are closed loops which never each other and the farther apart the field line are, the field. 5. Hans Christian Oersted discovered that magnetism and electricity are A magnetic field can be produced by the Current of electric charges. 6. Michael Faraday and Joseph Henry discovered that a changing magnetic field could produce More specifically, in the loops. This phenomenon is voltage will be induced in a loop of wire if there is a change in the the magnetic called 7. When a magnet is moved in and out of a coil of wire, voltage will be induced in the coil. If the rate of this in-and-out motion of the magnet is doubled, the induced voltage will be If instead the number of loops in the coil is tripled, the induced voltage will be 8. A rapidly changing magnetic field in any region of space induces a rapidly changing which in turn induces a rapidly changing generation and regeneration of electric and magnetic fields make up 9. A transformer This waves. is a device that can change the voltage applied to an appliance through set of coil of wires and a electromagnetic induction. This device consists of a set of coil of wires. The voltage output depends on the ratio of the coil of wires. 10. A primary transformer will have less turns in the primary coil and more turns in the secondary coil. For such a transformer, there is more voltage in the secondary coil compared to the primary coil, but there is less current in the secondary coil compared to the primary coil. However, the power in both the primary and secondary coil is the Same
