Fig.1
Cause of electric current in a closed loop - Changes in a magnetic flux that penetrates a closed circuit.
3) stage of obtaining new knowledge (built on the basis of solving experimental tasks)
Teacher: This phenomenon was first discovered by Michael Faraday in 1820. It was called electromagnetic induction.
ODA: Electromagnetic induction is a physical phenomenon consisting in the occurrence of a vortex electric field causing an electric current in a closed circuit when a change in magnetic induction flux through the surface limited to this circuit.
Teacher: Let's listen to the message about M. Faraday and its opening of this phenomenon. (Message of students)
OPR.: Current occurring in a closed loop is called induction.
Teacher: Consider all the occurrence of induction current in a closed loop. To do this, show a series of experiences, students should try to explain and indicate the cause of the induction current.
Experience 1: Making (submission) of a strip magnet from a closed contour connected to a galvanometer.
Current reason:
Experience 2.: Rotate the frame of one galvanometer connected to another galvanometer.
Current reason:rotate the frame in the magnetic field.
Experience 3: closure (opening) of the key; Move the retirement engine. (Fig. 3)
Current reason: Change magnetic induction.
Why does the magnitude and direction of the induction current depend on?
Experience: Magnet introduction to a closed circuit first with one magnet, then with two magnets. (Fig. 4)
Conclusion: The value of the current depends on the magnitude of the magnetic induction.
Experience: Magnet's introduction (submission) First North Pole, then the Southern Pole. (Fig. 5)
Conclusion: The direction of the current depends on the direction of the magnetic field.
Experience: make a magnet first slowly, then quickly.
Conclusion: The value of the current depends on the speed of making a magnet.
Teacher: To determine the direction of the induction current in the closed circuit used lenza rule: Induction current has such a direction that the magnetic flux created by it through the surface bounded by the contour, prevents the change in the magnetic flux that caused this current.
Apply this rule for the following cases: (Fig. 6)
(Two cases of the teacher disassembled himself, two other cases are performed by themselves in notebooks, two students can be called to the blackboard).
Demonstration of Lenza Rules

The wire frame rotates in a homogeneous magnetic field around the axis parallel to the field strength lines. Will there be an induction current in it?
How to move a closed wire rectangle in the magnetic field to the magnetic field so that the current is covered in it?
The ring from the wire listed in the rapid rotation between the poles of the electromagnet is noticeably heated. Explain this phenomenon. Will be heated under the same conditions a ring having a cut.
Experimental task: Fig.7 - In the steel core of the transformer connected to the voltage 220V (RNS), a closed loop with a light bulb is made. Why light bulb lights up?
Experimental task: Fig.8- The closed aluminum ring is planted on the steel core of the transformer connected to the RNSH. With increasing voltage to 220V, the ring gradually rises. The closed ring is replaced with a gap ring, and observe that the ring does not rise. Why?
