Magnetic Field Mathematical Formula

What is the magnitude and direction of the magnetic force acting.

Magnetic field mathematical formula. For example the number of field lines through a given surface is the surface integral of the magnetic field. The unit of magnetic field is the tesla t. This effect was first demonstrated by prof h c oersted in the year 1820. Magnetic effect of electric field is the property where an electric field is produced around a current carrying conductor.

The magnitude of the magnetic field depends on the amount of current and the distance from the charge carrying wire. Lorentz force on a charged particle of charge q in motion velocity v used as the definition of the e field and b field. The magnetic field is the space around a magnet or current carrying conductor around which magnetic effects can be experienced. The direction of motion of the protons is to the right of the page screen and the magnetic field direction is downward right at an angle of from the proton direction.

Here subscripts e and m are used to differ between electric and magnetic charges. The magnetic field formula contains the constant mu 0. These concepts can be quickly translated to their mathematical form. Besides the direction of magnetic field lines in the direction of your curled fingers.

And the magnitude of filed depends on the amount of current and the distance from the charge carrying wire. Furthermore it is a vector quantity and its si unit is tesla t or wbm 2.

The equation for the magnetic field strength magnitude produced by a long straight current carrying wire is. 1 a beam of protons each with charge is moving at through a uniform magnetic field with magnitude 0 60t. Magnetic force formula charge velocity questions. The formula includes the constant.

Where b is the magnetic field strength the magnetic flux density per unit area in teslas t a is the area of the surface and θ is the angle between the normal to the surface area i e the line perpendicular to the surface and b the magnetic field the equation basically says that a stronger magnetic field and a bigger area lead to more flux along with a field aligned with the. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A magnetic field is a vector field that describes the magnetic influence on moving electric charges electric currents and magnetized materials. Magnetic field due to a current element.
