A circulalr coil carrying a current of 0.5 A is initially set in the magnetic meridian. It is turned till the magnetic needle pivoted at its center becomes parallel to the plane of the coil. If in the position the plane of the coil is `30^(@)` away from the magnetic meridian, calcualte the horizontal component of the earth's magnetic field. (Radius of coil = 5cm and number of the turns = 50)
