In 1937, the patent for electromagnetic stirring (EMS) in electric arc furnace was granted to ASEA, who later merged with BBC to form ABB, in Sweden. Today, the technology plays a vital role in reducing consumption of energy and other resources for some of the largest furnaces and broadest continuous casters across the globe.

The initial temperature rise rate is simple. The input power to the coil is I^2R in Watts=Joules/second. That power is then heating the copper which has a mass and specific heat. The current will decrease as the coil heats up due to the increased resistance of the copper with temperature. The final temperature, as dpc says, is tough to determine.

This phenomenon is most evident when a magnet is dropped through a copper tube or near a copper plate, where the induced currents slow the magnet's movement—a process known as magnetic damping. This interaction also leads to practical effects such as heat generation from the resistance encountered by the induced currents.

At the same time, copper responds to magnetic fields mainly through its ability to create eddy currents while in contact with changing magnetic fields thereby utilizing its own magnets. This double property thus improves on electromagnetic applications like using it at electromagnet cores or magnetic levitation systems.

A: While copper is not magnetic, it can interact with magnets through electrical eddy currents. When a magnet moves near copper or other metals, it can induce these currents, creating a weak magnetic effect. Q: Why is copper not magnetic? A: Copper is not magnetic because it lacks the magnetic dipoles that align to produce a magnetic field.
