Hi, iam Norman Dolan, Don’t worry, it’s one day closer to the weekend.
Why A Soft Iron Bar Placed Inside A Solenoid Loses Its Magnetism Once The Current Is Switched Off? [Solved]
The soft iron bar acquires the magnetic properties only when an electric current flows through the solenoid and loses the magnetic properties as soon as the current is switched off. That’s why soft iron is used as the core of the electromagnet in an electric bell.
What is the effect of inserting a soft iron core inside a current-carrying solenoid?
