Electromagnets

The word "electromagnet" is composed of two words, ‘electro’ and ‘magnet’. It is a type of magnet in which an electric current helps in the generation of a magnetic field. Electromagnets usually consist of two major parts, wire and a coil around which the wire is wound. This is called a solenoid. When an electric current is allowed to pass through the coiled wire, the electric current produces a magnetic field. This magnetic field is present only when current is passing through the wire.

A transformer is to be used to provide power for a computer disk drive that needs 5.6 V (rms) instead of the 120 V (rms) from the wall outlet. The number of turns in the primary is 420, and it delivers 500 mA (the secondary current) at an output voltage of 5.6 V (rms). (a) Should the transformer have more turns in the secondary compared to the primary, or fewer turns? O There should be more turns in the secondary. O There should be fewer turns in the secondary. (b) Find the current in the primary. (c) Find the number of turns in the secondary. turns
In a well-designed transformer with an iron core, the secondary coil has twice as many turns as the primary coil. Which one of the followi statements concerning this transformer is true? OA This is a step-down transformer because the current in the secondary coil is less than that in the primary coll. OB The effect of the iron core is to reduce the magnetic field passing through the coils.
