1,it has uniform scale
2,with a power ful magnet its torqe to weight ratio is very high so operating current is small
3,the sensitivity is high

What describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?
moving a loop of wire through a magnetic Field. The rotation of a coil of copper wire trough a magnetic field changes magnetic field as "seen" from the coil inducing an alternating current.
Moving a conductor through a magnetic field a voltage is induced in the conductor is called what type of induction?
Moving a conductor through a magnetic field will produce alternatinc current (AC).
A conductor is moving perpendicularly to a uniform magnetic field Increasing the speed of the conductor will cause what to increase?
Voltage
What are the advantages of trading with a trading settlement as compared to just doing a two-way trade?
When you trade at the settlement, You can put on tremendous size and be filled without moving the market.
What is the current theory of the origin of magnetic fields?
Moving electric charges generate a magnetic field. This isn't a theory, it's a simple demonstrable fact. There really isn't a theory why this is true, it's just something that istrue."Spinning" charges also generate a magnetic field. I've got "spinning" in quotation marks because this applies also to charges that aren't actually physically spinning, but have a non-zero quantum spin number.
Does Magnetic forces act when electrons move?
Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one direction, than in the other.Yes.

What is the purpose of the permanent magnet in the moving coil meter?
The purpose of the permanent magnet in the moving coil meter is to measure electrical current. The coil will have a magnetic field which will react to the magnetic field of the permanent magnet. Since opposite poles attract, it will cause for the coil to move.Ê
Advantages of magnetic levitation?
Advantages of magnetic levitation for haptic interaction are:6-DOF motion with one moving partNoncontact actuation and sensingHigh control bandwidthsPosition resolution and sensitivity
Why is the Earth's core magnetic if its temperature is above the level at which metal is magnetic?
Moving electrical currents do NOT have an upper temperature limit. You're thinking if permanent magnets.
Advantages and disadvantages of maslow's hierarchy of needs?
Advantages - it is easy to understand Disadvantages - it is culture based, no mention of moving down the hierarchy, doesn't take into account changes over time, needs of employees are not all the same.
Is Earth permanent magnetic?
No.-----The earth has an important magnetic field.No, Earth would lose its magnetic field if its molten iron core were not moving. Scientists speculate that Mars had a magnetic field a long time ago but lost it when the planet cooled to the point that its core solidified.
What are the advantages of moving coil instrument?
Advantages are:- high sensitivity, uniform scale, very effective and reliable eddy current danping well shelded from any stray magnetic field. Disadvantages are:- very expensive, only suitable for direct current and voltages.
Is Venus a permanent magnet?
No.-----The earth has an important magnetic field.No, Earth would lose its magnetic field if its molten iron core were not moving. Scientists speculate that Mars had a magnetic field a long time ago but lost it when the planet cooled to the point that its core solidified.
What creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields. "A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom." A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.
Why does moving the magnetic field past the wire induce a voltage?
A good question. When an electron is moved, it will generate a magnetic force. In a permanent magnet, there are a 'magnetic domains' in which a number of electrons have similar spin direction. In an electromagnet, there are, by definition, a number of electrons moving in the same direction. If you do not have a moving electron, you do not have a magnetic field! From this statement, you may deduce that the amazing magnetic loops on the Sun, are generated by currents flowing inside the Sun.
What do magnet have to do with simple motors?
Motors convert electrical energy to mechanical energy through moving electric conductors through a magnetic field. Magnets can be permanent magnets or electromagnets.
What converts motion to electricity?
A wire moving through a magnetic field, or a magnetic field moving in relation to a wire.
