Don't understand with what the question want

  1. Dec 22, 2004 #1
    A long piece wire of mass 0.1kg and length 4.0m is used to make a square coil 0.1m on a side.The coil is hinged along a horizontal side,carries a 3.4 A current,and is placed in a vertical magnetic field of mahitude 0.01 T.

    (a)Determine the angle that the plane of the coil makes with the vertical when the coil is in equilibrium.

    I want to know what is meant by the 'square coil 0.1m on a side' phrase ?Is it mean each length of the coil is 0.1m ? or only one length is 0.1m and the other end is 3.9m making the dimension of the coil is (3.9 x 0.1) ?

    Thanks for anybody that spend sometime on this question .

    Something is wrong in the question. Either it is .4 m long and a square .1 m x .1 m. or it is 4 m. long and a square 1 m x 1 m.

    I think there is no mistake in the problem. The square coil has 10 turns.

    Each coil length = 4 X 0.1 = 0.4 m
    If the coil has 10 turns, total length = 10 X 0.4 = 4 m

    Your assumption is right Gamma and I can calculate the angle made between the plane of the coil and magnetic field.
