The displacement of the rod is largest when the direction of current is at right angles to the direction of the magnetic field.

Changing the direction of the magnetic field to vertically downwards results in the reversal of the force acting on the current-carrying rod.

The direction of the force on the conductor is reversed when the direction of current through the conductor is reversed.

The displacement of the rod suggests that a force is exerted on the current-carrying rod when placed in a magnetic field.

Ampère’s idea implies that there is a mutual interaction between magnets and current-carrying conductors, with the magnetic field exerting a force on the conductor and the conductor exerting an equal and opposite force on the magnet.

The force due to a magnetic field acting on a current-carrying conductor can be demonstrated through an experiment. Placing a magnet near the conductor and observing its movement or using a setup like Ampere’s law apparatus can showcase the interaction ...

French scientist André Marie Ampère (1775–1836) suggested that a magnet would exert an equal and opposite force on a current-carrying conductor.

The magnetic field produced by a current-carrying conductor exerts a force on a magnet placed in the vicinity of the conductor.

An electric current flowing through a conductor produces a magnetic field.

The strong magnetic field inside a solenoid can be used to magnetize a piece of magnetic material, like soft iron, when placed inside the coil. The resulting magnet is called an electromagnet.
