A magnetic field lines is an imaginary curve along which a free unit north pole tends to move. The tangent to the magnetic field lines at any point gives the direction of magnetic field at that point. Two magnetic field lines never intersect each other. It is vector quantity.

A moter is characterized by three main ingredients: magnetic field, moving charges, and magnetic force.

Properties of magnetic field lines: They are drawn locally as parallel trajectories. They never intersect each other (if they do, it means that one pole is pointing in two directions). They start from North and terminate at South, outside the magnet, and vice-versa inside.

Field characteristics The Earth's magnetic field is mostly caused by electric currents in the liquid outer core. The Earth's core is hotter than 1043 K, the Curie point temperature above which the orientations of spins within iron become randomized.

An electric field can be visualized by drawing field lines, which indicate both the magnitude and direction of the field. Field lines start on positive charges and end on negative charges. ... Another way to visualize field is to use field vectors, which are uniformly spaced.

Lines of Force around an Electromagnet The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.

In such a wave, time-varying electric and magnetic fields are mutually linked with each other at right angles and perpendicular to the direction of motion. An electromagnetic wave is characterized by its intensity and the frequency ν of the time variation of the electric and magnetic fields. Electromagnetic radiation.

A simple electromagnet consisting of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created. The strength of magnetic field generated is proportional to the amount of current through the winding.

Magnetic field strength is more a measure of current, i.e. curl H = J. Magnetic flux density is a measure of how much force will be applied to the motion of charges through it, i.e. F = qv cross B. Magnetic field strength does not incur force.

Magnetic field is non conservative in general, but in the special case of no currents and no time varying electric fields, it will act as a conservative field. NOTE: Any field with a curl will, in general, be non-conservative and magnetic field, indeed, has a curl (from Maxwell's laws of electromagnetism).

Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I). Light quanta are typically described by frequency (f), wavelength (λ), or photon energy (E).

An electric field can be visualized by drawing field lines, which indicate both the magnitude and direction of the field. ... The field vector at any point gives the direction of the field at the point, and the color of the vector shows the strength of the field.

Electromagnetic waves are formed when electric field couples with magnetic field. The magnetic and electric field are perpendicular to each other.

The magnitude of the magnetic field is 6.00 x 10-6 T, which can also be written as (micro-Tesla). The direction of the magnetic field can be determined using the "right hand rule", by pointing the thumb of your right hand in the direction of the current.

- The magnetic field is equal to the flux per unit area across an area at right angles to the magnetic field = magnetic flux density. - Magnetic force perpendicular to v → it cannot change the magnitude of the velocity, only its direction.
