Why does a solenoid what work??? How does a solenoid work??? And why it needs soft iron bar as core??? And why insulated copper wire is preferred in it???
Answers
Answer:
Explanation:
Solenoid is the generic term for a coil of wire used as an electromagnet. It also refers to any device that converts electrical energy to mechanical energy using a solenoid. The device creates a magnetic field from electric current and uses the magnetic field to create linear motion.
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the ironore is magnetized by induction. ... Thus, an electromagnet consists of a long coil of insulated copper wire wound on a soft iron core.
Copper shows high tensile strength, which is the measure of force needed to pull a wire till it breaks. Copper wires don't break easily when stretched. This prevents electrical interruptions and failures. The metal shows a unique combination of high ductility and high strength.
Answer:
solenoid is electric conductor carrying coil...
