Your compass needle will align itself with the lines of magnetic force at your location. This will diverge from the simple 'earth monopole model' depending on the local magnetic field, and any local geomagnetic anomalies.
On most topographic maps, the 'magnetic deviation' and its annual variance will be marked on the map legend. Where i am it is about 25 degrees east of the true magnetic north.
the vertical plane passing through magnetic axis is magnetic meridain and the vertical plane passing through geographical axis in geographical meridain.the intersting fact is they are not parallel...but remain at certain angle ..the maximum angle made is 17 degree
Since magnitude of magnetic force is given by, Fm = qvB sinθ,force will be maximum when θ = 90o So, magnetic force becomes stronger when a charged particle is moving perpendicular to the direction of magnetic field.
first of all the voltage doesn't change what changes is the current direction the way they do it is by using magnet . electrons tend to escape from the magnetic field . you can find on you tube how a motor works for better idea.
The deflecting force on a charged particle moving in a magnetic field is maximum when the charge moves perpendicular to the magnetic field lines. This occurs because the magnetic force acting on the charge is proportional to the velocity of the charge and the strength of the magnetic field, reaching its maximum when the angle between the velocity and the magnetic field is 90 degrees.
The layers of rock (strata) we see on the Earth's surface are rarely found in their original flat orientation. Measuring dip and strike is pretty easy, all you need is a compass for the level direction, and a clinometer to measure the vertical angle. For basic dip measurements I use an angle finder from a hardware store costing a couple of pounds (about 3-4 dollars US). I expect your tutor will expect you to sing the praises of the expensive "Brunton" combined compass and clinometer. (I don't know why, I have never found the point of spending huge amounts of money on this - but they remain a venerated item min American geology) Why bother? Measuring dip and strike is a fundamental part of geological mapping as you can build up a picture of the tilting and folding of the rocks beneath the surface, and start to build up a three dimensional model of the geology from the two-dimensional information at the surface. This is useful in predicting such things as the location and depth of an underground coal seam, or of working out the geological history of an area. If you cannot measure dip and strike directly, by measuring it off the surface of an exposed outcrop, then you can calculate it by measuring the height and direction an outcrop of the same strata run on opposite sides of a hill or valley, and doing some trigonometry.
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.
Magnetic flux through a surface is maximum when the direction of the magnetic field is in the same direction as the normal vector of the surface. In other words, the magnetic flux is maximum when the magnetic field is perpendicular to the surface area. That's why φ=BAcosθ, where θ is the angle between the direction of the magnetic field and the normal vector of the surface area. When the magnetic field is exactly the same direction as the normal vector (aka the magnetic field is perpendicular to the surface), θ=0 and cosθ = 1, its maximum value. The closer θ is to 90 degrees (ie. the more parallel the direction of the magnetic field is to the surface area, or the less parallel the magnetic field is to the surfaces normal vector), the smaller cosθ is, and thus flux will decrease accordingly.
A Berthold Pentrameter is similar to a pie gauge. It is used to determine current flow, magnetic field direction, sensitivity, and quality in magnetic particle inspection. A ferromagnetic piece is cut into quadrants, 90 degrees to each other on a rotating body. These cuts is will become visible when magnetic particle medium is applied and magnetism is applied. The body of the gauge is rotated to determin maximum indication direction, thusly you can determine the field direction which is 90 degrees to the indicated direction.
Iron cobalt, nickel and their alloys are magnetic; magnetic bars for stirrers, magnetic bars for maximum-minimum thermometers, magnetic souvenirs, etc. are examples of magnets.
The only way a compass can be used to create a circle is if you draw round it, because a compass is actually a navigational instrument which shows direction. If you're out in the woods, for example, you use a compass to show you which direction you need to head in. A pair of compasses can be used to construct, or draw, a circle of any size, up to the maximum reach of the "arms".
When the wire is perpendicular to the magnetic field, the force on the moving charges in the wire is maximized because the magnetic field exerts a force perpendicular to both the field and the direction of current in the wire. This results in the maximum Lorentz force acting on the charges in the wire, leading to the maximum overall force experienced by the wire.
