Complete the following diagram of magnets to show the lines of force.

A circular loop placed in a plane perpendicular to the plane of paper carries a current when the key is ON. The current as seen from points A and B (in the plane of paper and on the axis of the coil) is anti clockwise and clockwise respectively. The magnetic field lines point from B to A. The N-pole of the resultant magnet is on the face close to

A wire 10 cm long carrying a current of 1.5 A is held in a uniform magneÑic field in which B = 10-3 T. Calculate the force on the wire if it is held perpendicular to the lines of the magnetic field.
