A spinning copper disc is slowed down when a magnet is brought near it. Note that copper is not a magnetic material.
Eddy currents are induced in the disc due to the relative motion of the disc and the magnet. The magnetic fields associated with these currents have such a direction that they oppose the cause that created them in the first place (Lenz rule). As a result they oppose the relative motion between the disc and the magnet and hence the disc is slowed down.
This Consumertronics video tutorial shows you how kilowatt-hour meters work and their anatomy with simple, detailed instructions. Also, demonstrates an actual Stopping Power Meters Educational Module (SPMEM) in action and external magnetic (IG MANUAL) methods used to slow and stop KW-HR meters!
