Electromagnetic Fields
Technically, the term "electromagnetic field" (EMF) refers to all fields throughout the electromagnetic spectrum. In common usage, however, the term usually refers to so-called extremely low-frequency… More »

where B is the magnetic field (the unit of magnetic field is the Tesla (T)). You should note that the field direction has been set by the requirement that F is perpendicular to v. However, it ensures that if we use a compass needle to map out the field the north pole will point in the direction of the magnetic field.
