Question-

We can convert a bar of iron into a magnet by?

Answer-

From the concept of the right-hand thumb rule, we can say that the magnetic force’s direction is given by the right-hand thumb, which in the direction of velocity, the magnetic field’s path is given by the direction of fingers and the direction of magnetic force is in the perpendicular direction to the palm. Let us consider that an iron rod is acting as a core of the long solenoid carrying current.

Due to the flow of current, a magnetic field is generated in the rod. The magnetic field lines of the solenoid are uniform, parallel in direction, and have high strength. The magnetic field lines around the solenoid carrying current are similar as in the case of a bar magnet that is termed as the north pole and south pole. The iron molecules will act like small magnets, which covert rod into a magnet as a combined effect. We also know that iron is a ferromagnetic material as a result of its molecules will align in the direction of magnetic force.
