Magnetic Phenomena From Rotating Current-Carrying Wire

When a loop current carrying wire rotates continuously, it generates a magnetic field, which interacts with the surrounding environment. This interaction creates several physical phenomena, including electromagnetic force, torque, and electromotive force (EMF). The magnetic field produced depends on the current flowing through the wire, the number of turns in the loop, and the rotational speed.
