What are the three classification of magnets?
Permanent MagnetsPermanent magnets are those we are most familiar with, such as the magnets hanging onto our refrigerator doors. They are permanent in the sense that once they are magnetized, they retain a level of magnetism. As we will see, different types of permanent magnets have different characteristics or properties concerning how easily they can be demagnetized, how strong they can be, how their strength varies with temperature, and so on.Temporary MagnetsTemporary magnets are those which act like a permanent magnet when they are within a strong magnetic field, but lose their magnetism when the magnetic field disappears. Examples would be paperclips and nails and other soft iron items.ElectromagnetsAn electromagnet is a tightly wound helical coil of wire, usually with an iron core, which acts like a permanent magnet when current is flowing in the wire. The strength and polarity of the magnetic field created by the electromagnet are adjustable by changing the magnitude of the current flowing through the wire and by changing the direction of the current flow.
How would you use energy level in a sentence?

How do you do temporary adjustment of dumpy level?
It as 3 following steps to adjust the dumpy level 1.SETTING 2.LEVELLING.3FOCUSING
Difference between auto level and tilting level?
In the auto level, no adjustment for staff reading is required as the actual reading is seen from the eyepiece. In the dumpy level, to level the bubble, one has to keep the bubble parallel to two leveling screws and then right angle to the third screw. ... The line of sight is manually adjusted in the dumpy level.

What is the difference between a theodolite and a dumpy level?
In dumpy level we can check only horizontal angles whereas in theodolite we can check vertical angles also.
Why is dumpy level known as dumpy level?
It is named so because of the shorter telescope it uses and also because in the original dumpy level the eye piece was an inverting lens such that it gave a shorter view for the same power of lens compared to wye level.
What are parts and functions of a dumpy level?
You can find all of these parts by looking up the diagram of a dumpy. They are available with a simple image search.
What are the fundamental axes of dumpy level?
i honestly dont know
How do you use dumpy level to find the relative heights?
Dumpy level provides a horizontal line (parallel to earth's curvature); you can read the scale by holding it normal to the ground level. Take separate readings for separate points then compare them
How do you calibrate a dumpy level?
AIM/PURPOSE: To describe the instruction for the calibration of Dumpy Level to ensure that equipment is maintained in fully serviceable condition, is safe to operate and meets environmental requirements. FOR THE CALIBRATION OF DUMPY LEVEL The method described below is to be used on-site check prior to use as to the accuracy of the Dumpy level between calibration checks. This Work instruction shall be conducted at the commencement and completion of a contract. 1. Drive two pegs, "A" & "B", into the ground six metres or more apart 2. Set Dumpy up at "C" 3. Shoot a level at "A" and "B" 4. Relocate Dumpy to "D" and shoot a level at "A" and "B" 5. Record the appropriate result in the workbook. (Levels shot at "D" should be within ± 10mm of "C") D A C B
