The bent wire shown in Fig. lies in a uniform magnetic field. Each straight section is 2.0 m long and makes an angle of \(\displaystyle={57}^{\circ}\) with the x axis, and the wire carries a current of 2.0 A.

(a) What is the net magnetic force on the wire in unit-vector notation if the magnetic field is 4.0 T?
(b) What is the net magnetic force on the wire in unit-vector notation if the magnetic field is 4.0 T?

(a) The net magnetic force on the wire in unit-vector notation if the magnetic field is 4.0 T is 8.0
(b) The net magnetic force on the wire in unit-vector notation if the magnetic field is 4.0 T is zero
Since the field and current are in same direction.
0
