Magnetic Effect Of Electric Current<\/a><\/strong><\/h2>\n

You know that magnets can attract certain substances such as iron. So far, you have studied about electricity and magnetism separately. However, did you know that electricity and magnetism are closely related? Perform the following activity to understand this.<\/p>\n

Activity<\/strong><\/h3>\n

Aim:<\/strong> To see the magnetic effect of current passing through a wire (adult supervision required).
\nMaterials needed:<\/strong> 1.5 V cell, two pieces of insulated wire, a small magnetic compass, and insulation\/adhesive tape.
\nMethod:<\/strong><\/p>\n

    \n
  1. Strip the insulation from the two ends of both the wires.<\/li>\n
  2. Connect one end of one of the wires to the negative terminal of the cell. Secure the connection with the insulation\/adhesive tape.<\/li>\n
  3. Connect one end of the other wire to the positive terminal of the cell. Secure the connection with the insulation tape.<\/li>\n
  4. Place the magnetic compass near the wire.<\/li>\n
  5. Keep an eye on the needle of the magnetic compass and touch the free ends of the wires connected to the positive and negative terminals of the cell.<\/li>\n<\/ol>\n

    \"What Observation:<\/strong> When the wire touches the positive terminal of the cell, the needle of the magnetic compass gets deflected (moves).
    \nConclusion:<\/strong> This is because when a current passes through the wire, it behaves like a magnet and therefore deflects the magnetic needle of the compass.
    \nNote:<\/strong> Follow the precautions given on p. 182 while doing this activity.<\/p>\n

    We have seen in the above activity that a current-carrying conductor behaves like a magnet. As a result, it can deflect a magnetic needle.
    \nWrap a wire around a soft iron piece (known as the core). When an electric current is passed through the wire, the iron piece behaves like a magnet. A magnet made using such an arrangement is called an electromagnet<\/strong>. A solenoid<\/strong> is a device which can be used as an electromagnet. It is made of a long wire that has been wound many times (usually around a hollow metallic core) into a tightly packed coil, it has the shape of a long cylinder.
