In fact the Earth is moving away from the Sun - due to the Suns mass loss - at a mere 15cm per year.
That means that in a hundred years, we will be almost 15 metres further away - hardly worth worrying about.
Planets that have a magnetic field have: 1) Contains magnetic material like iron, ionized gases, hematite, or magnetite. 2) Has a magnetic current going thru the material. If the planet does not contain enough magnetic material or the material does not have enough magnetic current, there is no magnetic field.
Not necessarily. Comets can rotate in either direction on their axis, some rotate counterclockwise while others rotate clockwise. The direction of rotation is determined by various factors such as the direction the comet formed or collisions it may have experienced.
same as earth
All planets in the solar system rotate, but not all in the same direction, Mercury, Earth, Mars, Jupiter, Saturn, and Neptune all rotate in one direction, while Venus, Uranus, and the dwarf planet Pluto rotate in the opposite direction.
No. The Earth rotates counter-clockwise around its own axis, when viewed from above its North Pole. Venus rotates in the opposite (clockwise) direction, around its own axis, when viewed from 'above'. The Earth's magnetic poles wander as much as 15 km every year and reverse or "flip" with an average interval of approximately 250,000 years. Presumeably, this can also happen on any of the other planets that happen to have magnetic poles. However, Venus does revolve counter-clockwise around the Sun, as observed from 'above' the Sun's 'north pole.' The Earth also revolves counter-clockwise, as do all of the other planets that revolve around our Sun.
In this electric motor, an electric current flowing through the coil interacts with the magnetic field, generating a force that causes the coil to rotate. This rotation changes the direction of the magnetic field around the coil, which in turn causes the coil to keep rotating in the same direction.
Cooling fans use electric motors which operate by magnetism. As the direction of the current flow reverse, the magnetic poles reverse and hence the change in direction.
no
Yes, it is possible to orient a current loop so that it does not tend to rotate in a uniform magnetic field. This can be achieved by aligning the plane of the current loop perpendicular to the direction of the magnetic field. In this configuration, there will be no net torque acting on the loop, thus preventing it from rotating.
you rotate left
A compass utilizes magnetism to indicate direction by aligning itself with the Earth's magnetic field. The needle inside the compass is a magnet that is free to rotate, and it points towards the Earth's magnetic north pole. This allows the compass to show the direction of north, south, east, and west based on the orientation of the needle.
An ordinary compass indicates the direction of magnetic north, which is the direction a magnetic needle points due to the Earth's magnetic field. The needle is balanced on a pivot, allowing it to rotate freely and align itself with the magnetic field lines. This tool is commonly used for navigation and orientation, helping users determine their heading relative to the cardinal directions: north, east, south, and west.
Planets that have a magnetic field have: 1) Contains magnetic material like iron, ionized gases, hematite, or magnetite. 2) Has a magnetic current going thru the material. If the planet does not contain enough magnetic material or the material does not have enough magnetic current, there is no magnetic field.
A compass is a free-spinning magnet that will align itself to be parallel to the Earth's magnetic field lines. Since the Earth's magnetic poles are located relatively close to its geographic poles, a compass pointing to Earth's magnetic north pole also indicates the general direction of Earth's geographic north pole.
Magnetic materials (materials capable of becoming magnets), such as iron, have the capability to form small magnetic regions, called "magnetic domains". In these, the atoms are oriented in a preferential direction, causing the magnetism; when an external magnetic field is applied, the domains themselves rotate, so that more of them point in one direction than in the other. In that case, the material is magnetic.A magnetic field may also be caused by an electrical current. This is used in electromagnets.
The operation of an electric motor depends on the interaction of magnetic fields, passing of electric current through coils of wire (armature), and the resulting electromagnetic forces that cause the motor to rotate. The direction of the current and the arrangement of the magnetic fields determine the direction of the rotation, while the flow of current and the strength of the magnetic fields dictate the speed and torque of the motor.
If you sample a section, you have a specific direction in which you have drilled your sample. By applying a rotation matrix containing the bearing and the plunge of the drilling direction to the measured direction of your magnetic vector you rotate your measured vector (in core coordinates) to geographic coordinates. This vector would be true, if since the deposition the position of your section would not have changed. But usually tectonic forces have lifted, tilted and moved your section. By measuring the dip and dip direction (or strike) of the stratigraphy in the section, you can apply another rotational matrix to your vector and rotate it back to horizontal, which as a result gives you the direction of the magnetic field during deposition.
