What else can I help you with?
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.
What is a small magnet that can turn freely and always point north?
A compass.A compass.A compass.A compass.
Do convection currents always affect the same way?
No, convection currents can vary in strength and direction depending on factors such as temperature gradients, fluid properties, and boundary conditions. In general, convection currents result from the movement of fluids due to differences in temperature, but the specific behavior can be influenced by a variety of factors.
Do magnets have to touch each other in order to experience a magnetic force?
not always as the south pole of a magnet is magnetic yet it repels another south pole. :D
Can direct current produce magnetic flux?
Moving electrons always have a magnetic field around them
Does a compass needle always point directly northward in the absence of other nearby magnets or currents?
In the absence of interference from other magnetic fields or currents, a compass needle will align itself with the Earth's magnetic field and point towards the magnetic North Pole. However, it may not always point directly northward due to local magnetic anomalies or declination.
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 an electric current produce a field magnetism around it?
yes. electric current low always generates 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.
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 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.
Are currents always present in the ocean?
yes they are
How does magnets produce electricity?
An electric current will always be surrounded by a magnetic field. The reason for the relationship is not exactly obvious; it has been explained by Albert Einstein in his paper "On the electrodynamics of moving bodies".
