Do convection currents always affect the same way?
no
Does a compass needle line up perpendicular or parallel to a magnetic field?
A compass needle will align itself with a magnetic field. It will want to lie along the magnetic field lines, or lie parallel to the lines of force of the magnetic field it is interacting with.
How are magnetic poles and electric charges similar?
Main similarity: Like charges repel each other, different charges attract each other.Main difference: Magnetic "charges" can't be separated. At least, so far it has not been achieved.
Is the magnetic pole near the Earths true North Pole a magnetic south pole or a magnetic north pole?
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.
Do earth's magnetic field has always run from north pole to south pole?
Yes a magnet has a north pole and a south pole. Magnets generate a magnetic field that "flows" in one direction. To make it easy to understand how two magnets interact, scientists and physicists assign names of "North" and "South" to the opposite ends of the magnet. Some magnets can reverse direction.
Can direct current produce magnetic flux?
Moving electrons always have a magnetic field around them
Are electric currents magnetic?
A magnetic field is always associated with a moving charge. So, if current is there, it must be showing the magnetic effects though these are too small of daily relevance..
Does electricity always produce a magnetic force?
Magnetism, an aspect of electromagnetism, one of the fundamental forces of nature. Objects such as a bar magnet can influence other magnetic materials, without physically connecting them, because magnetic objects produce a magnetic field. Magnetic fields are usually represented by magnetic flux lines. Magnetic fields influence magnetic materials and also influence charged particles that move through the magnetic field.
What 1 major difference between bar magnets and electroagets.?
Electromagnets only have a magnetic field when electrical current if flowing through them. When the power if off, so is the magnetic field. A bar magnet ALWAYS has a magnetic field.
Can a electric current runnng along a wire be used to produce a magnetic force?
Whether or not you use it, there's always a magnetic field surrounding an electric current.When anything that can respond to a magnetic force is brought close enough to the current,it does feel a magnetic force.
Can an electric current produce a field magnetism around it?
yes. electric current low always generates a magnetic field.
Is that brain contains magnetic field?
Question is confused, but try this... The brain does generate electrical fields, and they do change, and since changing electrical fields always generate magnetic fields ... then YES. However ... the electrical fields of the brain are of very low magnitude and are relatively slow to change (as compared to any manufactured gadget), so the brains magnetic fields are weak and are considered minor The electric field is the source code for EEG's.
Are northern currents always cold?
No
Are currents always present in the ocean?
yes they are
Are the magnetic in the north pole and the geographic north pole always the same distance?
No, the magnetic pole is always on the move, which is why the magnetic variation is often printed on maps.
Why does gravitational force predominate over electric force for astronomical bodies?
It acts over long distances; and (unlike electrical and magnetic forces) it is always attractive, so its effect is cumulative.
Which waves have some electrical properties and some magnetic properties?
The answer is electromagnetic waves.
