Take a rod of iron. Tightly wind the copper windings on it. Connect the end of wire to a battery .
What will happen if the soft iron rod is replaced by a steel rod?
Will the coil still behave like a magnet if the soft iron is removed?
How does the strength of the magnet gets affected if the battery of double voltage connected?
Dear Student ,
1. If it is replaced by steel then it produces minimum electricity ,
2. It will behave as a magnet for some time after removing the soft iron ,
3. If the battery of double voltage is connected then double amount of current will pass through the electromagnet creating its magnetic effect more .
