Homework Statement
A coil of wire consisting of 40 rectangular loops, with width 16 cm and height 30 cm, is placed in a constant magnetic field given by
B = 0.055Tx + 0.210T.z
The coil is hinged to a fixed thin rod along the y-axis (along segment da in the figure) and is originally located in the xy-plane. A current of 0.150 A runs through the wire.http://www.webassign.net/bauerphys1/27-p-051.gifWhat are the magnitude and the direction of force, Fbc, that B exerts on segment bc of the coil?
magnitude Fbc =
direction °
What are the magnitude and the direction of the torque, t, that B exerts on the coil?
magnitude t =
The Attempt at a Solution
i am just lost
i have the formulas but I'm not sure how to find the magnitube for B
hints pleasE?
