Def: Magnetic fields surround magnetic materials and electric currents and are detected by the force they exert on other magnetic materials and moving electric charges. The magnetic field at any point is specified by both a direction and a magnitude. It is a vector field.
Mathematically:
For instance, a particle having an electric charge (q), and moving in a magnetic field (B) with velocity (v), experiences a force (F), called the Lorentz force
F= q (v×B)
SI unit:
In SI units the strength of magnetic field is given by tesla (T).
Some of the unit conversions are
1 tesla = 1 weber/square meter
1 tesla = 1 maxwell/square meter
1 line/square centimeter = 1 gauss
1 line/square centimeter = 100000 gamma
