Which metal is used to make up the dial of watch to minimize the magnetic effect?
1.gold 2copper 3steel 4brass
How do you move a toy car without touching it?
put a co2 (carbon dioxide) cartridge on the end of your toy car, co2 cartridges could be balloons or any empty object you can put air into, once done let the co2, or air go and watch your toy car fly like a monkey without a bannana or use a fan
How magnetic sensors work?
The answer depends on what type of magnetic sensor you are speaking of. One type might be a reed switch. In the presence of a magnetic field the switch changes state, either opened to closed or closed to open. I'd consider this one the simplest type of sensor. Either the field is strong enough to cause the state change or it isn't. Another type I'd consider to be more of a transducer. According to physics' proof and the ideas of a guy from long ago named Faraday, a changing magnetic field (this field is also said to be in a state of "flux" when changing) in the presence of a conductor will induce a voltage proportional to the rate of change of the field. Mathematically stated this is written as e = k do/dt where e is the voltage induced, k is a constant of proportionality, and do/dt (the derivative of phi, o, with respect to time) is the rate of change of the flux. (Note: o is supposed to be the Greek letter phi, but I haven't a convenient means of entering it, and I don't remember the ASCII code.) Anyway, so this e voltage that's developed can be measured with a voltmeter or via an oscilloscope and is proportional to the rate of change of the magnetic field. Rarely would a magnetic field remain constant. Therefore, one can always expect some amount of potential to be developed no matter how small. However, you may be asking, 'but what about the field itself. How would the field's strength be detected?' The do/dt in the above equation is the key. Just the same way that o can be differentiated (called "taking the derivative" of) to obtain do/dt, do/dt can be integrated (the opposite/inverse of differentiation) to obtain o. However, it should be understood that there must be a time period involved, because integration is, simply stated, the area under the curve. You can't have an area without a width. Therefore, when integrating we're taking a bunch of infinitessimally small-width rectangles and summing them over a period of time (because time is the independent variable in the above equation and not something else.) So, leaving the Calculus aside except for the above equation, the way the magnetic field is detected is the voltage e that's developed must then be applied across a load. For example, we could just measure it with a voltmeter, but that voltmeter itself is a load, a very high resistance load. When that load is applied, a current flows due to more physics and the theories of another guy long before television named Ohm (if there is a closed loop for the current to flow in.) Ohm's Law (actually, I'm pretty sure it's still a theory, but they call it a law) states: voltage = current x resistance or e = i x r or The potential, e, developed across a resistance is proportional to the current flowing through the resistance. (Notice that e gets larger as i gets larger?) Hence, rearranging Ohm's Law to solve for i we have (and I'm going to write the equation downward this time): e = ir therefore e -- r = ir -- r therefore i = e -- r So (saying it like a normal person now) we have i = e/r What this says is we can produce a current proportional to the voltage developed by applying that voltage across a load. Hence, to sense the strength of the magnetic field, we can integrate the rate of change of the flux over time, or, if we're only interested in whether the field is present or not, we can read the voltage developed whenever the field changes. Either way we have sensed the magnetic field. There's one other way to sense a magnetic field and it's by way of another phenomenon of physics called "The Hall Effect." However, I regret that I don't remember enough about it to explain it very well. In a nutshell, a voltage is developed in the presence of a magnetic field within (usually) a semiconductor material by the magnetic force causing drifting positive charges to go one way and negative charges to go the opposite way thus producing a difference of potential across the material. That difference of potential is called the "Hall voltage" or "Hall emf" (electromagnetic force, voltage). However, with this short explanation I really do not do Edwin Hall (another guy who didn't watch tv) justice. And I'd really appreciate it if someone more knowledgeable will post an update to this answer which does explain it.
What is the difference between a gold watch and a golden watch?
A gold watch is made of gold ,on the other hand golden watch is gold in color.
What is the difference between a Seiko automatic watch and a Seiko kinetic watch?
A Seiko automatic watch has less battery power than a Seiko kinetic watch. So if one purchases an automatic watch, they'd have to wear it daily. The kinetic watch has stronger battery power.
A watch made of circular ring on top has the minute and hour hand made of magnetic material. Explain why the hands are not affected when the watch is placed in a magnetic field?
Does an automatic watch run slow if it gets magnetized?
I suppose it could, yes - it will stop if the magnetic field is strong enough.
Is the bracelet on a rolex watch magnetic?
No

How many people where there to watch the first flight by the wright brothers?
Five persons.
What layer of the atmosphere is the northern lights?
Solar Radiation --answer-- Solar radiation - consisting mainly of electrons and protons and other particles - interacts wit the Earth's magnetic field, generally in the polar regions (north and south) where the field is strongest.
Is it really true that the magnetic watch from 007 can reflect gun bullets?
Bullets are generally made of lead, with or without a jacket of gilding metal. Those are not affected by a magnetic field- only ferro-magnetic metals such as steel and iron are attacted to a magnet. And the magnet would be the size of a large truck, and needs it's own powerplant to operate it. Sorry- what looks good in the movies, and what works in real life are sometimes quite different.
What is the effect of magnetic field on aluminium?
Aluminum is non-magnetic, but does interact with magnetic fields. Aluminum isn't normally magnetic, but as you carry a large aluminum tray towards the magnet, you find that the magnet repels the aluminum, why? Lenz's law. The magnet induces a magnetic field in the moving aluminum tray to oppose it's own, effectively pushing it away. As long as the tray doesn't move, it experiences no magnetic forces. But when you drop it, it falls past the magnet remarkably slowly. When the tray is stationary the magnetic field is not changing, but as soon as it moves, the field begins changing and an opposing field is induced. If you want to test this, and you should, because it's cool, find a rare earth magnet and an aluminum tube. Drop the magnet into the tube and watch how it takes many times as long to fall through. Also look up eddy currents on aluminum, they can be produced by spinning a magnetic field, and shoots aluminum cans off of conveyor belts.

Yes, both soccer and football are played on the same field .

Will NASCAR fans watch football?
NASCAR fans will watch football. Though races may interfere with football because of the time of the race and game, fans can watch both sports. It's possible to like more than one sport.
