Question

define magnitude of magnetic field

Answer 1

The magnitude of the magnetic field is 6.00 x 10-6T, 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.

Answer 2

The magnetic field B is defined from the Lorentz Force Law, and specifically from the magneticforce on a moving charge: ... Themagnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field.
