is China's national college entrance examination examination, physical examination every year can always see the year title and level of students, in physics class, the current sensor is a regular, look at current sensor for the college entrance examination questions is what kind of?



Such as topic experiment topic, 26 demo experiment device of the existence of geomagnetic field (by the toroid, micro electric current sensor, Orcus, etc). First place vertical coil, in vertical direction for shaft rotation, there comes the current pointer on the screen (fill: & other throughout the &; or & other no & throughout;) Deflection; Then will remain upright coil, make its plane parallel to the east-west, and is moving from east to west, the current pointer ____ (fill: & other throughout the &; or & other no & throughout;) Deflection; Finally will coil placed, make its move from east to west, the current pointer ____ (fill: & other throughout the &; or & other no & throughout;) Deflection.
Examination is how to make use of a given instrument demonstration of the geomagnetic field exists, and in the physics teaching basic requirements, there are: & other; Our country has developed a moon, if the astronauts to the moon to detect whether there is a magnetic field on the surface of the moon, after his hand there is a sensitive current sensor and a square turn more small coil, and sensitive to current sensor and the coil form closed loops, so he is able to infer what kind of conclusion correctly? Throughout the &; It's obvious that the two problems of the examination site, but the university entrance exam questions and in the Angle of the subject, in the form of thinking and difficult to change, by making coil forms of exercise, is examines the student's understanding to produce induced current conditions, and test of the students' understanding of the earth's magnetic field and the ability to form the concept of space in your mind. This is derived from books, there is no lack of again the innovative questions, really can distinguish between those & other; True & throughout; Comprehensive grasp the physical basic knowledge, have a certain ability, flexible thinking, good at suitable candidates to enter college study.

This paper increased part points the topic the difficulty of Watson sensor, this is especially apparent in the first part of the single topic selection, students from & other; Want to also don't want & throughout; It can be done to & other; Think about it & throughout; Do it again, compared with previous years, the difficulty increases. With number 12, with the aid of the door alarm circuit test knowledge about logic circuit; 14, examination is the knowledge of the vibration and wave, in the topic of this class examination site is simple, whereas this year some of the master, test questions from the perspective of rhetorical questions, examination, etc, all have a deep and improve, which requires students to these knowledge not only stay in the know & other; What is & throughout; , more know & other; Why & throughout; .
In the worst-hit areas of the students lose points in the previous years & mdhistriadn; & mdhistriadn; Experimental test and calculation, the difficulty is reduced. Computational problems, four basic test did not change, still adhering to the gas, Newton's laws of motion, the order of the electric field and electromagnetic induction, the electric field of the topic tactfully with the use of images, graphics, analysis the ideas of physics and force, electricity knowledge combined with flawless, played down the demand for mathematical operation, to strengthen the examination of students' physical thinking quality.
