Question

a) Describe the existence of magnetic force on electric current carrying conductor

in a magnetic field. Obtain equation for the force.​

Answer 1

Figure 1. The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges). ... The force on an individual charge moving at the drift velocity vd is given by F = qvdB sin θ.

Answer 2

${\mathtt{\huge{\red{\underline{Hey \: Mate \: !!}}}}}$

❛The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges). Noting that V = Al, where A is the cross-sectional area of the wire, then the force on the wire is F = (qvdB sin θ) (nAl)......✔
