A wire of length 1 m is placed perpendicular to a uniform magnetic field of magnitude 2 T. What is the magnetic force on wire when the current flowing through it is 3 A?

Answer 1

Use the expression that F= i l x B or |F| =ilB sin Θ in this problem Θ = 90° so the force on the wire is

F= 3(1) (2) = 6 N
