magnetic field of 0.15 T?
What is the magnitude of magnetic force per unit length on a wire carrying a current of 8 A and making an angle of 30º with the direction of a uniform magnetic field of 0.15 T?

Solution
Current in the wire, I
= 8 A
Magnitude of the
uniform magnetic field, B = 0.15 T
Angle between the wire
and magnetic field, θ = 30°.
Magnetic force per unit
length on the wire is given as:
f
= BI sinθ
=
0.15 × 8 ×1 × sin30°
=
0.6 N m–1
Hence, the magnetic
force per unit length on the wire is 0.6 N m–1.
