What is magnetic paint?
Magnetic paint is just like regular latex paint, except for the fine particles of iron dust mixed throughout which gives it a special magnetic quality. When applied to a surface, you end up with a layer of primer with many tiny flecks of iron spread throughout. Magnets are attracted to these flecks of iron transforming your project into a magnetic surface.
What element gives brimstone its bad smell?
Sulfur does. It appears in the form of a compound with oxygen: sulfur dioxide.
What does adornment mean?
An adorner is someone who adds adornment to something. An adorner gives extra beauty to a thing by adding a decorative element.
What is the gravitional field strength of the earth at its surface?
The gravitational field strength of a planet multiplied by an objects mass gives us the weight of that object, and that the gravitational field strength, g of Earth is equal to the acceleration of free fall at its surface, 9.81ms − 2.
How many protons do lutetium have?
An element's atomic number gives its number of protons. Lutetium's atomic number is 71. Thus, it has 71 protons.
What gives rise to the Earths magnetic field?
Current flows inside he Earth.
A loop of wire is placed in a uniform magnetic field.In which orientation of the loop is the magnetic flux linked with it maximum?
1. The orientation giving the maximum magnetic flux would be 90 degrees or perpendicular to the magnetic field because that gives the maximum amount of magnetic field lines able to pass through the area of the coil. The greater density of field lines gives a greater magnetic field. The orientation that would give a magnetic flux of zero is the plane of the coil to be parallel to the magnetic field, making no lines pass through the coil and thus no flux.
What is the classical explanation of a dc electric current in a metallic wave?
A changing magnetic field always produces an electric field, and conversely, a changing electric field always produces a magnetic field. This interaction of electric and magnetic forces gives rise to a condition in space known as an electromagnetic field.
What gives earth it's magnetic field?
in 1872 3 scientists dug to the earths core and implanted an electro magnet more powerful than an atomic bomb. The government kept all this secret so that no one could disrupt the magnet's current.

What is Van Vleck paramagnetism?
When we apply external magnetic field, the orbital levels of electrons are rearranged themselves. Final vector sum of the orbital moment along the direction of magnetic field gives van vleck contribution.
What is a magnetic field and how does it work?
Magnetic field is produced by varying electic field. It is a vector quantity. It originates from North pole and passes to south pole and it is a closed loop.Magnetic forces gives information about charge carriers in a material through Hall effectansw2. A magnetic field may be a fixed one - it does not need to vary. Consider a permanent magnet.All magnetic fields are caused by the movement of electrons. No moving electrons - no magnetic field.The Earth's magnetic field is created by electrical currents, running roughly parallel with the equator. There may be several such paths - we see the net effect.

Why does the compass respond when it is near a electrical wire with current flowing through it?
Because electricity gives off a magnetic field.
Do force-field exist?
Yes. There is only one problem. Its just that it is 1cm cubed. Very tiny. And obviously, the mathematical one which gives of a magnetic force field exists.
What happens when you add more coils to the wire in an electromagnet what else can you do to increase the magnetic field of an electromagnet?
The more loops gives the magnet more voltage. More loops produce more currents. The current that is induced as acts like an opposing magnet and makes it more difficult to move the magnet.
Earth revoles on its axis true or false?
Yes, it does though it wobbles a bit. This gives us seasons and the magnetic field that a compass detects.
