Where on Earth’s are the magnetic field lines parallel to its surface?
Answer and Explanation: Magnetic lines of force are parallel to Earth's surface at the equator.
Are Earth’s magnetic field lines parallel?
Several magnetic parameters vary across the surface of the globe. For example, the angle at which magnetic field lines intersect Earth's surface, known as the inclination angle, varies predictably with latitude. At the magnetic equator, field lines are parallel to Earth's surface and the inclination angle is 0 deg.
Where are magnetic force lines?
The magnetic lines of force, indicate the region in which the force of the magnet can be detected. This region is called the magnetic field. The magnetic lines of force, or flux, leave the north pole and enter the south pole.
When magnetic lines of force are parallel to a closed surface?
There will be no net magnetic flux through the surface. Here in question it is given that magnetic lines of forces are parallel to the surface so there will no magnetic field lines will pass through the surface. And if there is no magnetic field though the surface then there will not any magnetic flux produced.
Where do magnetic lines of force enter Earth quizlet?
Field lines enter Earth near the North Pole. The magnetic pole near Antarctica is a north pole.
Where is the Earth’s magnetic field located?
the outer core Earth's magnetic field is generated within the outer core by the convective movement of liquid iron, but as we discovered in Chapter 8, the magnetic field is not stable over geological time. For reasons that are not completely understood, the magnetic field decays periodically and then becomes re-established.
Where is the most magnetic place on Earth?
The south magnetic pole intersects the Earth at 78.3 S latitude and 142 E longitude. This places the south magnetic pole in Antarctica. The magnetic poles are also where the magnetic fields are the strongest.
Where are the magnetic field lines closest together and what does that tell you about the strength of the magnetic field?
By convention, the lines trace the force from the north to south pole of a magnet. The distance between the lines indicates relative strength of the magnetic field. The closer the lines are, the stronger the magnetic field is.
What are magnetic lines of force?
Magnetic lines of force are imaginary lines that represent the direction of the magnetic field as we move from one pole to the other. The magnetic lines of force can be compared to rubber bands in that they contract when the magnetic force is removed and expand when the magnetic force is increased.
What does the parallel magnetic lines of force indicate?
(c) If magnetic field lines are parallel and equidistant, they represent zero field strength.
Why are magnetic field lines parallel?
In a uniform magnetic field, the field lines are parallel equidistant straight lines. Following are the properties of the magnetic field: The magnetic field lines do not cross over each other. The magnetic field lines are always in a closed-loop moving from the north pole to the south pole.
How are the magnetic field lines near the south?
How are the magnetic field lines near the south pole of a magnet affected when a second south pole is brought near it? The field lines bend away from the second south pole. A bar magnet and a second object are hung from metal rods. The diagram below shows what happens when both objects are released.
In which direction do the magnetic field lines point near the south pole of a magnet quizlet?
In which direction do the magnetic field lines point near the South Pole of a magnet? Outside the magnet the direction of magnetic field lines is towards the South Pole of the magnet.
On what layer of the Earth does the Earth’s magnetic field originate?
Earth's magnetic field is generated within the outer core by the convective movement of liquid iron, but as we discovered in Chapter 8, the magnetic field is not stable over geological time.
Which part of the Earth is responsible for the magnetic field?
Earth’s core The crust of the Earth has some permanent magnetization, and the Earth's core generates its own magnetic field, sustaining the main part of the field we measure at the surface.
Which layer is responsible for Earth’s magnetic field?
The outer core The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth's magnetic field. As Earth spins on its axis, the iron inside the liquid outer core moves around.
Where does Earth’s magnetic field originate?
Scientists know that today the Earth's magnetic field is powered by the solidification of the planet's liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space.
Is the earth’s magnetic field parallel to the ground at all locations if not where is it parallel to the surface is its strength the same at all locations if not where is it greatest?
It is nearly parallel at the greater and it is nearly perpendicular to the surface near the pools. So they can write the olds magnetic field is not parallel to the ground at our location, it is parallel at the equator and nearly perpendicular at pools.
Where do the magnetic field lines converge?
Solution : (i) The ends of a current carrying solenoid behave as magnetic poles. One end behaves as north magnetic pole and field lines diverge from it. Other end of solenoid behaves as south magnetic pole and field lines converge there.
Why do magnetic field lines go from north to south?
When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.
What is the direction of magnetic lines of force inside the magnet?
The direction of magnetic lines of force of a bar magnet is from north to south pole outside the magnet and from south pole to north pole inside the magnet as shown in figure.
Why are magnetic lines of force parallel inside the solenoid?
Solution : Magnetic lines of force inside the solenoid being parallel to each other means that the intensity of the magnetic field inside the solenoid is uniform at every point.
Why are magnetic field lines parallel to each other inside a solenoid?
The magnetic field lines in the middle of a current-carrying solenoid are parallel to the axis of the tube because the magnetic field is uniform inside a solenoid.
Can magnetic field lines be parallel to the direction of current flow?
Answer: nope they are always opposite in the direction of current…..
Why is there no force when magnetic field and current are parallel?
This is because the magnitude of the force depends on the sin of the angle between the direction of current and the direction of the magnetic field, so if the current-carrying wire is held parallel to the magnetic field, the force will be zero.
Does magnetic force go from north to south?
The magnetic field lines of a simple magnet are shown in the picture below. They point from the north pole to the south pole. However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole.
How are the magnetic field lines near the south pole of a magnet?
Terms in this set (10) How are the magnetic field lines near the south pole of a magnet affected when a second south pole is brought near it? The field lines bend away from the second south pole.
Which layer of the Earth produces the Earth’s magnetic field?
outer core The Earth's outer core is in a state of turbulent convection as the result of radioactive heating and chemical differentiation. This sets up a process that is a bit like a naturally occurring electrical generator, where the convective kinetic energy is converted to electrical and magnetic energy.
Which layer of Earth’s interior produces the Earth’s magnetic field and how?
Differences in temperature, pressure and composition within the outer core cause convection currents in the molten metal and earths spin result in whirling movements of the liquid metal resulting in generation of electric currents and there by producing magnetic field.
Where does Earth’s magnetic field come from?
Generated by the motion of molten iron in Earth's core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun.
