Magnetic fields

Question 1

Radius of curvature

Answer 1

mag force is perpendicular to the velocity vector of the charged particle, hence the magnetic force provides a centripetal force, and the particle will move in a circular path

Question 2

define the tesla

Answer 2

strength if the magnetic flux density that produces a magnetic force of 1 newton in a wire of length 1 m with 1 ampere flowing perpendicular to the field
