Ratings and Reviews for  Lenz's Law Demo

4 / 5

The plastic elements quickly fell from the magnet, I had to glue them back. Still, the thing does what it's meant to. I'm very satisfied.

It works, although the buffer pads on the magnets / weights could be better secured, and had to be re-glued after a few demonstrations.

Lenz's Law: This could be improved with a smaller viewing port, so that the retardation effect is more pronounced. Other purchases: Heatmobile2: Very good, but subject to rust on the lower axle. Thus, it requires periodic servicing for optimal function. Tippe Top (small): Durable and very well produced. Inverter Magnet kit: impressive. Perhaps it could be sold with the small scale to determine friction of table and hence enable field-strengths to be estimated.
