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?
The Earth's magnetic field is generated by the movement of molten iron in the outer core, driven by heat from radioactive decay and the cooling of the planet. This movement creates electric currents, which in turn produce a magnetic field around the 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 inside a magnet that gives it its magnetic properties?
Inside a magnet, there are tiny particles called atoms that have their own magnetic fields. These atoms align in the same direction, creating a magnetic field that gives the magnet its magnetic properties.
What does the relative density of lines of a magnetic field tell us about the strength of the field?
The relative density of lines in a magnetic field diagram indicates the strength of the magnetic field in that region. A higher density of lines represents a stronger magnetic field, while a lower density indicates a weaker field. The spacing between the lines also gives an idea of the field's intensity, with closer lines indicating stronger magnetic force.
Where does the magnetic force come from within the earth?
The magnetic force within the Earth comes from the movement of molten iron and nickel in the outer core. This movement generates electric currents, which in turn create a magnetic field. This magnetic field is what gives the Earth its north and south magnetic poles.
What gives earth its magnetic force 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.

Why does the compass respond when it is near a electrical wire with current flowing through it?
The compass responds to electrical currents because the flow of current generates a magnetic field around the wire. This magnetic field affects the compass needle, causing it to align with the direction of the field. This phenomenon is known as electromagnetic interference.
What does atoms have that make an object magnetic?
Atoms have unpaired electrons in their outer energy levels that create a magnetic field when they align in the same direction. This alignment of magnetic moments is what gives rise to the magnetic properties of an object.
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.

An electric current flowing through a wire gives rise to a magnetic field whose direction depends upon what of the current?
The direction of the magnetic field produced by an electric current flowing through a wire is dependent on the direction of the current. The right-hand rule can be used to determine the direction of the magnetic field relative to the direction of the current flow.
