What is the electromagnet? Draw a circuit diagram to show low a soft iron piece can be transformed into an electromagnet. |
Answer» Solution : The magnetic FIELD produced due to current flowing in a coil or a solenoid can be used to magnetise a material like SOFT iron TEMPORARILY. The insulated copper wire is wrapped on a soft iron piece. When current is PASSED through the coil using a battery and a key the iron piece BEHAVES like a bar magnet as long as current is being passed. Such a magnet is called an electromagnet. |
