The cheap and easy way that we did in school long ago was to put the magnetic on a table, lay a sheet of paper on top, and sprinkle iron shavings on it. I don't know if that always works, but it did for our experiment.
If you are looking to measure the Gauss of the magnet. I would see how much force is exerted on a steel bar and search the internet to see if there are some simple formulas.
Depending on what you're looking for, I can provide more help.
use compass..... or if u want to determine the madnetic field direction in a current carring material, then apply right hand rule .. thumb should be in the direction of current and curl of finger will tell u the direction of magnetic field
Get a magnet that's free to turn in any direction ... a boy-scout compass will do nicely.
Place it in the magnetic field. It rotates to point in the direction of the field 'lines' at
that location. (I forget whether it's the north or south pole of the compass that points
in the direction of the magnetic field, or opposite to it.)
If you like, move your detector slowly, always following the direction in which it points,
and you'll trace out a complete 'line' of the magnetic field.
One easy way to accomplish this is to sprinkle iron shavings in the vacinity of the bar. The shavings will allign themselves in the shape of the magnetic field.
If you have a compass and it points towards north
errrm get a compass and use
No. It has. Since transverse electric mode has it's wave propagating in the Z direction, and has magnetic field existing in the same direction with NO electric field... Likewise, transverse magnetic mode has it's wave propagating in the Z direction and has electric field existing in the same direction with NO magnetic field.
The direction of a magnetic field is defined by the direction in which a compass needle will point when placed within that field -that is, from north to south.
It is where the magnetic field have the same magnitude and direction in a specific region. Hope that helps
The earth maintains a magnetic field due to the metals that make up its core. Thus, all rocks are influenced by this magnetic field and "face" the direction the field is "facing". Every few hundred million years the poles switch, and with it the magnetic field. Similarly, all rocks "face" the new direction. Magnetic strips are indicators of when the magnetic field of the Earth changed.
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this
perpendicular to the magnetic field direction
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
No. It has. Since transverse electric mode has it's wave propagating in the Z direction, and has magnetic field existing in the same direction with NO electric field... Likewise, transverse magnetic mode has it's wave propagating in the Z direction and has electric field existing in the same direction with NO magnetic field.
The direction of magnetic field lines are from north to south
It is a way of representing the magnetic force at a point in the field. The magnitude and direction of the vector represents the strength and the direction of the magnetic force acting on a charged particle in the field.
The direction of a magnetic field is defined by the direction in which a compass needle will point when placed within that field -that is, from north to south.
A magnetic field is neither: it is a vector field with both direction and quantity.
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
It is where the magnetic field have the same magnitude and direction in a specific region. Hope that helps
By knowing the precise orientation of the rocks magnetic field, you can compare its magnetic field direction to the known direction of the magnetic field over time since the "north pole" wanders over time. The rock locked in its magnetic field when it cooled from magma.
The conducting wire wrapped around the compass is energized creating a magnetic field that counteracts the effects of the Earth's magnetic field and changes the direction of the compass needle.
