9. Blackboard design Ⅰ 、 Lenz’s Law The induced current or induced e.m.f . will be established in a direction so as to produce effects which oppose the change that is producing it   Ⅱ 、 Faraday’s Law for magnetic induction An emf is induced in a conducting coil of N turns if the magnetic flux through the coil changes. The magnitude of the emf is equal to the rate of change of the magnetic flux: Magnetic flux: Φ B =B • A unit: Weber 1Wb=1T ·㎡ Magnetic flux linkage:   Minus sign: direction of the induced current.

10. Reflection There ‘re some problems in time control. Some graphs are not easy to distinguish
