Question

How can we predict about the strenght of magnetic field in a space?

Answer 1

Magnetic field written in term vector potential we can determine the strength of magnetic field.another way by magnetometer we can measure the strength of magnetic field.

Answer 2

Answer:

Magnetic field can be written in terms of vector potential an by determining the potential we can find the strength.

The strength of a magnetic field in space can be determined by a magnetometer. This device measures the 'strength and direction' of a magnetic field. Space-based or vector magnetometers are used for measuring the magnetic field in space. A magnetic field is pictorially represented as magnetic field lines in an area.
