2. What is an Electromagnet?
Magnet is considered cool as all kinds of fun experiments can be done with their help, but the usefulness of magnet is limited. The magnet always attracts, which is sometimes needed like in a fridge. However, the usage of electromagnets changes that, and the application becomes endless. An electromagnet is made by wrapping a copper wire around a soft iron core either in the U-shape or the shape of a solenoid. When current flows through the coil wrapped on it, it behaves as an artificial magnet.
3. How can the Strength of Electromagnet be Increased?
An electromagnet is a temporary strong magnet that is made of a soft iron core. The strength of the magnetic field in electromagnets can be increased by the following methods:
By increasing the number of turns in the coil, and
By increasing the current through the coil.
Whether the core is made up of a soft or hard magnetic material, soft iron will magnetize more readily than steel. Therefore, using a softcore increases the strength of the electromagnet.
4. Name the Material that is Used for Making the Armature of an Electric Bell. Give a Reason for Your Answer.
Soft iron is used in the armature of an electric bell because it induces magnetism rapidly. The armature of the electric bell needs to show magnetic properties only when it is magnetized otherwise it behaves as a non-magnetic material. This means that the material used for making the armature of the electric bell should magnetize quickly as the electric current passes through them and de-magnetize quickly as the electric current stops. The soft iron shows weak or temporary magnetic properties. When the button of the electric bell is pressed, the circuit in the electric bell closes and the current starts flowing through it. Due to this current, the armature of the electric bell made up of soft iron gets magnetized, hits the gong and bell rings.
