What is the difference between magnetic track and magnetic heading followed by airplanes?
As a defence America needs to develop a magnetic drone shot from the ground, attach itself to the bottom of an aircraft and intercept its mainframe to be controlled from the ground
What is the duties of oceanographer?
Oceanographers study the ocean, so mainly they research about the ocean. A big job for oceanographers is keeping track about Tsunamis. Tsunamis are very destructive and they need the help of seismologists to track them.
What is the difference between a train and electromagnetic train?
A typical train has wheels and rolls on metal rails. It's drive wheels are driven by a steam engine, a Diesel engine, or even electric motors powered by the rail system or overhead wires. An electromagnetic train, on the other hand, does not ride on wheels, or have an engine, per se. It is suspended from it's track by a powerful magnetic field generated by electro-magnets in the track and train. In addition to providing suspension of the train, the magnetic fields are used to propel the train itself, so it does not need an "engine" at all.
Would a magnetic compass be suitable to be used for space travel . if not what kind of equipment would you suggest?
In a word, no. A conventional magnetic compass only indicates the *Earth's* magnetic field. The influence of any extraterrestrial magnetic fields falls off according to the inverse-square law, that is, the force is diminished by the square of the distance from the source. What this means is that any fields present from other objects are very small compared to the Earth's own field. You can demonstrate this by influencing a compass with a small bar magnet. Once you leave the vicinity of Earth, the usefulness of a magnetic compass disappears almost immediately. Of present technology, Inertial Navigation is the most suited for space travel. By using accelerometers and gyroscopes to measure acceleration along each axis, and rotation around each axis, you can keep track of distance and direction traveled. That's how spacecraft got to the moon, planets and beyond the solar system. Addition: A sextant will always be a handy navigational tool. If interstellar travel ever becomes a reality a real time pulsar triangulator will be a necessity. Every pulsar has a unique rotational frequency. By triangulating apparent angles between the pulsars a spacecrafts position in space can be known.
Where did the UARS crashed?
NASA isn't exactly sure. The satellite had failed, so it was difficult to track. But they're sort-of confident that it fell into the north Pacific ocean.
Can you float a person with magnetic force?
Yes, they have already built trains which are held above the track by magnetic fields, they are called Maglev trains(magnet levitation).
How are magnetic trains designed and shaped?
Magnetic trains such as the MagLev are designed and shaped in such a way that they do not come into contact with the railway track but instead are suspended above a guideway and are propelled by magnetic fields. Levitation is achieved by either electromagnetic or electrodynamic suspension.
How Does Magnetic Track Lighting Work?
Magnetic track lighting utilizes a magnetic track system installed on the ceiling, allowing for the easy attachment and movement of light fixtures along the track. The magnetic connection simplifies installation and allows for quick adjustments, making it a flexible choice for various lighting applications.
What are magnetic field lines and how do they show the strength of a magnet?
Magnetic fields are bascially lines of force caused by magnetic poles. It is invisible, but you can track how the field lines are formed doing a small experiment. Spread some iron fillings on a tray. Then bring a magnet up close to the iron fillings but not too close. You can observe that the iron fillings move into the field lines of the magnet that you brought up close. That's a miniature of a magnetic field. The earth's magnetic field is much bigger.
What are the events in athletics?
Track and fields
What is the rule of Sports officiating in track and fields?
no steroids
What is principle of maglev train?
Magnetic levitation is the method used for maglev trains. In order to levitate a train, superconducting magnetic coils are used to completely expel the magnetic fields which will cause the trains to fly off its track.
Where is the friction on maglev train?
If you have two magnets they each have a north and south pole. The opposite poles will attract and the same poles will repel. Maglev trains create magnet fields on the track bed and the train of the same polarity. By controlling the generating of the fields you can hold up the train and propel it forward. Since the train is not actually touching a track there is no appreciable friction except that caused by the surrounding air. In a vacuum you would have no friction.
What do you call the subdivision of a track on magnetic disk or optical disk?
A sector
How high is the tippickle pinewood derby track?
The height of a typical Pinewood Derby Track is about 4 feet, from the floor to the top of the track.
When was track and fields started?
probaly around the time of the Greeks or Romans
What is the number of read-write heads in the drive for a 9-track magnetic tape?
16
