About This Product
Lenz's law says that the current induced in a conductor by a changing magnetic field flows in a direction that opposes the change that caused it. In class, a magnet is moved towards loops that can swing on a needle. A closed aluminium loop carries an induced current and is pushed away or pulled by the magnet, while an open loop has no complete circuit and shows little movement. Comparing the two shows why a closed path is needed for the opposing effect.
