Question

14. What will happen to the strength of a solenoid if we use a soft iron rod inside it?​

Answer 1

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

Answer 2

Explanation:

. 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. ...Complete step by step answer:When a soft iron rod also known as the core is inserted inside a solenoid then the strength of the magnetic field increases because the iron ore gets magnetized due to magnetic induction and this combination of the solenoid and the soft iron core is called an electromagnet.The simplest motion producer is a solenoid, which consists of a coil with a soft iron core (or armature) which slips easily in and out of the coil. Soft iron is used because it does not retain its magnetism when the current is switched off; in other words, it does not become permanently magnetized.
