He does seem a little upset >> At least he was 3 years ago when he made the video >> Feb 11, 2014
and he may NOT have done it on purpose BUT on the older wheel meters a magnet in the correct place WILL reduce the speed of the wheel and hence reduce the electric bill
A common method of tampering with electric meters is by attaching magnets to the outside of the meter. These magnets prevent the alternating current from forming eddy currents in the rotor, by saturating the coils or current transformers.
Quoted from >> Tampering And Security In Electric Meters Discussed By Experts
The new improved digital meters are supposed to be built so a magnet will not affect it
"Meters should offer compliance to requirements of CBIP-304 and its amendments for tampering using external magnets. The meter should be immune to tamper using external magnets. The meters should be immune to 0.2T of A.C. magnetic fields and 0.5 T of D.C. magnetic fields, beyond which it should record as tamper if not immune."
The above statement is a requirement during the manufacturing of digital energy meter. Hence we shall assume that digital meters are tamper proof using Magnets.
