A magnetic field of 1.4 T [N] is 4.0 m wide. A very long wire crosses the field.
a)If the current in the wire is 2.0 A [W], find the magnetic force on the wire.
b)What will happen to the force on the wire if:
i)the wire is rotated slightly in the horizontal plane?
ii)the current is doubled?
iii)the magnetic field is reversed?
PLEASE help, show work!
thankyou

By F = iBLsinθ
(a) F = 2 x 1.4 x 4 = 11.20 Newton (downward in the paper)
(b) (i) F(net) = F x sinθ = 11.20sinθ Newton
(b)(ii) F(net) = 2F = 22.40 Newton
(b)(iii) F = 11.20 Newton (upward in the paper)
