Question

In a high magnetic field experiment, a conducting bar carrying10.0 kA passes through a 30 cm long regioncontaining a 30.0 T magnetic field. If thebar makes a 30° angle with the field direction, what force isnecessary to hold it in place?
______kN I keep getting 80 as my answer. any help would be great.
