[1.(c))Without removing the battery, and using the same items in the diagram above, state one other way you can change the set-up to get the same observation in (b).[1 相关知识点: 试题来源: 解析 a.The two magnets' like poles are facing each other, making both of the ...
The fixed part of the motor is called the “stator”. Permanent magnets are used to provide a stationary magnetic field. Normally these magnets are positioned on the inner surface of the stator, outside of the rotor. In order to create torque, which makes the rotor spin, the magnetic field...
They were nearing Chicago. Signs were everywhere numerous. Trains flashed by them. Across wide stretches of flat, open prairie they could see lines of telegraph poles stalking across the fields toward the great city. Far away were indications ofsuburban67towns, some big smokestacks towering high ...
The Earth's geographic North Pole is near a magnetic south pole. Explain why. What will happen if you try to place two bar magnets of exactly equal size one above the other such that their north poles are on the same side? What are magnetic poles?
When a body is taken from the equator to the poles, what will happen to its weight?Gravity:The gravitational force between the two masses is given as, F=G M mr2. we can see that as the distance between the two masses is decreased then the force of gravitation...
aIn the rotor structure, all the rotor teeth protrude out of the magnets surface, forming a number of spiral air channels equal to the number of spiral magnet poles. When the motor rotates, the spiral magnet poles play a role as a sirocco fan to accelerate the air directed to the gap, ...
When an object is at .distances of μ1 and μ2 from the poles of a concave mirror, images of the same size are formed. The - focal length, of the mirror is A∣μ1+μ2| B|μ2+μ1| C|μ1+μ22| D|μ1−μ22|Submit II. Read the following text and answer the following ques...
Two big mirrors A and B are fitted side by side on a wall. A man is standing at such a distance from the wall that he can see the erect image of his face in both the mirrors. When the man starts walking towards the mirrors, he finds that the size of his face in mirror A goes...
